Whereas the latter two present with language disturbances, FTD is characterised by five core clinical criteria, all of which had to be present to make a diagnosis of FTD. Background: Inter-rater accuracy of the diagnosis of AD has been explored, but there are few accuracy studies for progressive supranuclear palsy (PSP) and frontotemporal lobe dementia (FTD). Confirmation of diagnosis is important for families, and in the advancement of research. Frontotemporal dementias (FTDs) are a group of clinically and neuropathologically heterogeneous neurodegenerative disorders characterized by prominent changes in social behavior and personality or … People with FTD typically first come to the doctor’s office because of: Gradual and steady changes in behavior The earliest changes typically include a disregard for social conventions, impulsivity, apathy, loss of sympathy or empathy, repetitive or compulsive movements, dietary changes and poor insight, planning and assessment. Management of problematic FTD features is challenging, and establishing a working relationship between a primary care physician and a cognitive/behavioral neurologist or psychiatrist, along with a neuropsychologist with expertise in non-pharmacologic modes of behavior management, is strongly advised. In 2011, the International Behavioural Variant FTD Criteria Consortium (FTDC) proposed revised criteria as the 1998 criteria were considered to be too rigid for clinical and research purposes . In some instances, such as when behavioral dyscontrol or marked irritability is present, medications can decrease these features. Research studies and clinical trials are gaining momentum. 1 FTD is thought to be the third most common type of dementia after Alzheimer disease (AD) and dementia with Lewy bodies.FTD is also a common type of early-onset dementia (occurring among … Since the publication of the Strong cr … The criteria for diagnosing post-traumatic stress disorder (PTSD) in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders () are somewhat different than the criteria in the fourth edition.Here are the symptom criteria in the DSM-5. All features must be present to fulfill the criteria for diagnosis. Often this is asymmetrical. For example, behavioral variant frontotemporal dementia (bvFTD) is sometimes misdiagnosed as a mood disorder, such as depression, or as a stroke, especially when there are speech or movement problems. Supportive diagnostic features. Measurement of CSF phospho-tau, total tau and Beta-amyloid can sometimes support the diagnosis of FTD over Alzheimer’s disease. endobj Methods 178 consecutive neuropathologically ascertained cases initially diagnosed with a FTD syndrome were collected through specialist programmes: the Cambridge Brain Bank, UK, and Sydney Brain Bank, Australia. Behavioural variant FTD with definite FTLD Pathology Criterion A and either criterion B or C must be present to meet criteria. Frontotemporal dementia (FTD) refers to a group of disorders caused by progressive nerve cell loss in the brain's frontal lobes. The prodromal phase of dementia with Lewy bodies (DLB) includes (1) mild cognitive impairment (MCI), (2) delirium-onset, and (3) psychiatric-onset presentations. Frontotemporal dementia (FTD) describes a clinical syndrome associated with shrinking of the frontal and temporal anterior lobes of the brain. Despite advances in the understanding of the behavioral variant of frontotemporal dementia, the diagnosis of the syndrome remains challenging. This topic will review the clinical features and diagnosis of the main clinical syndromes of FTD. The core clinical criteria for the diagnosis of mild cognitive impairment (MCI) due to Alzheimer’s disease and Alzheimer’s dementia can be applied to clinical practice immediately. Blood work should be done to exclude alternative causes of cognitive symptoms, including a basic metabolic panel, CBC, RPR, ESR, B12 level and thyroid studies. In this section you will learn the essential facts about FTD. The diagnosis of FTD requires a thorough history, verified by a caregiver, and a neurological examination. Prominent early symptoms include progressive coarsening of personality, social behaviour, self-regulation (of emotions, drives, and behaviour), and language. Neurology 2011 March 15; 76: 1006 – 1014. Frontotemporal dementia is much less common than other types of … These developments should gradually promote enhanced assessment of more patients using advanced tools. A definitive diagnosis of FTD can only be made post-mortem via autopsy of the brain. The prevalence of bvFTD varied between 0.2% and 0.5% at age 70 to 79 years, … Some individuals seek rehabilitation services. Pathological diagnoses included FTLD-tau, … Frontotemporal dementia (FTD) is a neu­rologic disease that affects the frontal and the temporal lobes of the cerebral cortex. This means FTD can be hard for doctors to diagnose as they may not recognise its symptoms as dementia. With single-photon emission CT, we diagnosed 30 patients with FTD. In this section you will learn how you can volunteer your time and talents, raise much-needed funds, and provide your own generous donation. FTD has broader criteria. Historically, these disorders have not been clearly demarcated from AD. As this is an invasive procedure, the value of additional information to be gained should be discussed with patient and family. 1 This disorder is observed most often in people between age 45 to 65, but also can manifest in younger or older persons. Mutations of genes involved in FTD and others dementia were excluded [apolipoprotein E, amyloid precursor protein, presenilin 1 and 2, microtubule-associated protein tau, progranulin (GRN), PARK7]. <> These three sets of diagnostic criteria include different combinations of impairments in social and emotional abilities. With single-photon emission CT, we diagnosed 30 patients with FTD. 1 0 obj The use of multiple testing, however, increased the probability that some statistically significant likelihood ratios … King of Prussia, PA 19406, ©2020 It is recommended that the individual see a genetic counselor first, to be sure they understand the implications of this testing. For bvFTD, consensus clinical criteria (Raskovsky et al., 2011), together with a finding of frontal lobe atrophy on MRI or perhaps a negative amyloid PET scan, can render a diagnosis with great confidence, said Dickerson. The term frontotemporal dementia (FTD) describes a group of neurodegenerative disorders that are characterized by the clinical syndrome of progressive dysfunction in executive functioning, behaviors, and language. OBJECTIVES The diagnosis of Alzheimer’s disease (AD) is now reliant on the use of NINCDS-ADRDA criteria. or email [email protected].

FTDs typically appear in mid-life, with peak onset in the sixth decade. As with other degenerative diseases, FTD presents an insidious onset and progresses over time. Autopsy evaluation of a patient with FTD can be daunting to a general pathologist. As with other degenerative diseases, FTD presents an insidious onset and progresses over time. The early symptoms and the brain image are often the most helpful tools to reach the right diagnosis. A subset (n = 1074) underwent computerized tomography (CT) of the brain. There are no medications which are FDA-approved for the management of FTD-related features. This topic will review the clinical features and diagnosis of the main clinical syndromes of FTD. Two members of AFTD’s Medical Advisory Council – Bradford C. Dickerson, M.D. The diagnosis of FTD requires a thorough history, verified by a caregiver, and a neurological examination. All patients should be screened for obstructive sleep apnea (OSA), as executive dysfunction and behavior changes are common in OSA. They show functional changes in brain glucose metabolism, and are often positive earlier than MRIs. A full neuropsychological testing evaluation should be used to better assess the pattern of cognitive loss in an individual suspected of having FTD and to help rule out psychiatric etiologies for an individual’s symptoms. Some of the major advances reflected in the new criteria include: (i) reduced number of diagnostic features; (ii) no … – presented a Clinicopathological Conference at Massachusetts General Hospital to demonstrate a differential diagnostic process in neurodegenerative disease. Based on the accumulated experience with the 1998 criteria (Mendez and Perryman, 2002; Mendez et al., 2007; Rascovsky et al., 2007a; Piguet et al., 2009), the International Behavioural Variant FTD Criteria Consortium developed revised guidelines for the diagnosis of bvFTD. Overview. 135 cases were reclassified using the revised diagnostic criteria into behavioural variant (bvFTD), semantic variant PPA (sv-PPA), non-fluent/agrammatic variant PPA (nfv-PPA) and logopenic variant PPA (lv-PPA). Criterion C can be positive for possible bvFTD but must be negative for 3 0 obj Frontotemporal dementia is an umbrella term for a group of uncommon brain disorders that primarily affect the frontal and temporal lobes of the brain. Many primary care physicians are uncomfortable making the diagnosis of FTD. When the diagnosis is uncertain, referral to a neurologist with an interest in cognition and behavior and/or a geriatric neuropsychologist is indicated. BvFTD is the most common variant of FTD.   Bring help and support to the next family affected by FTD. FTD has broader criteria. In one series based on 433 cases from an academic memory clinic between 1991 and 2003, specificity was 99% and sensitivity 85% ( Knopman et al ., 2005 ). Rascovsky, K, Hodges, JR, Knopman, D, Mendez, MF, et al. Four years after the FTD diagnosis… We scored every patient on each LMRC item and compared the two groups. Neurology 2013; 80: 496 – 503. Historically, these disorders have not been clearly demarcated from AD. Patients and their families can be pointed to AFTD’s page on the Genetics of FTD for more information.

ftd diagnosis criteria

Table 3. International consensus criteria for behavioural variant FTD (FTDC) I. Neurodegenerative disease: The following symptom must be present to meet criteria for bvFTD 1 The cause varies among a range of pathologies affecting the anterior portions of the brain. This article presents the revised consensus criteria for the diagnosis of frontotemporal dysfunction in amyotrophic lateral sclerosis (ALS) based on an international research workshop on frontotemporal dementia (FTD) and ALS held in London, Canada in June 2015. spatial disorder were also consistent with an FTD diagnosis. When a family history is positive, genetic testing of the diagnosed patient can be undertaken. If the classic features of OSA are present (e.g., loud disruptive snoring, snorts and apneic pauses while sleeping, crowded oropharynx, excessive daytime sleepiness, repetitive desaturations on overnight oximetry), then referral to a sleep medicine specialist and polysomnography is indicated. Lumbar puncture is another test that can be used to rule out mimicking conditions (infection, immune etiologies, carcinomatous and paraneoplastic syndromes). In addition, diagnostic accuracy is complicated by recent reports of patients with features of bvFTD but who show little or no progression over many years. The pattern of change in electroencephalography is nonspecific in FTD; often the test is normal. The SPECT scan is less costly, but it reflects blood flow more than metabolic change, and is felt to be less sensitive for FTD. Criteria for the diagnosis of corticobasal degeneration. Frontotemporal Dementia (FTD) Primer Frontotemporal dementia (FTD), also known as frontotemporal lobar degeneration (FTLD), or less commonly, Pick's disease, is the most common causes of dementia in adults younger than 60 years. Classification of primary progressive aphasia and its variants. The 2010 criteria for diagnosis of bvFTD require 3 out of the following 6 symptoms to be present:. Frontotemporal disorders can be hard to diagnose because their symptoms—changes in personality and behavior and difficulties with speech and movement—are similar to those of other conditions. Psychiatrists are helpful when behavioral or emotional problems are predominant. <>>> Since the publication of the Strong cr … Methods: 178 consecutive neuropathologically ascertained cases initially diagnosed with a FTD syndrome were collected through specialist programmes: the Cambridge Brain Bank, UK, and Sydney Brain Bank, Australia. Clinical imaging may help researchers better understand changes in the brains of people with FTD, as well as help diagnose these disorders. Gorno-Tempini, ML, Hillis, AE, Weintraub, S, Kertesz, A. It is characterized by uninhibited behavior, hyperorality, lack of empathy, impaired executive function, and lack of sympathy. The criteria for each of the three major clinical syndromes are divided into sections. FTD is one of the more common causes of early-onset dementia, with an average age of symptom onset in the sixth decade. Methods for bedside assessment of behavioural variant frontotemporal … How do you know if it’s FTD? Most of these are directed by neurologists, though an interested geriatric psychiatrist or geriatrician may also be appropriate. Originally known as Pick’s disease, the name and classification of FTD has been a topic of discussion for over a century. They are therefore not necessary conditions for diagnosis. Armstrong, MJ, Litvan, I, Lang, AE, Bak, TH, et al. With the exception of occasional genetic causes, today there is no single test that can diagnose FTD with certainty. Imaging of neurodegenerative cognitive and behavioral disorders: practical considerations for dementia clinical practice. It provides additional supportive evidence for the FTD diagnosis, keeping in mind that some patients perform within normal limits when features are mild. The clinical profile statement together with the core clinical inclusion and exclusion features provide the necessary foundation for diagnosis. Clinical. The same is true for FTD’s language variants. In the final stages, patients typically require 24-hour care. FDG-PET scans are more specific, but are costly. No single test can identify frontotemporal dementia, so doctors attempt to identify certain characteristic features while excluding other possible causes. A discriminant function showed that loss of personal … Although nonspecific, this testing is easily obtained at many hospitals, is less costly, and it is relatively noninvasive. Other diseases causing dementia are being increasingly recognised—for example, frontotemporal dementia (FTD). FTD strikes earlier in life than other dementias, which can devastate family relationships, finances and even the health of caregivers. These patients were compared with 30 with a research diagnosis of Alzheimer's disease (AD). Long-Term Care for FTD. It covers some of the feelings you might have and suggests ways of staying positive. Bigio (see below) provides a step-wise histochemical and immunohistochemical approach to investigation for the general pathologist conducting an autopsy on a decedent with FTD. Their simplified criteria subsume progressive aphasia and semantic dementia under the rubric of FTD and consist of the following six features: (1) early and What are ways to help an individual diagnosed? 4 0 obj The clinical diagnostic criteria were revised in the late 1990s, when the FTD spectrum was divided into a behavioral variant, a nonfluent aphasia variant and a semantic dementia variant. Other projects are aimed a better understanding the toxic effects of protein buildup and how it is related to the development of FTD and related dementias. Brain 2011 Sept; 134:2456 – 2477. 1 The cause varies among a range of pathologies affecting the anterior portions of the brain. Frontotemporal dementia / Pick's disease – learn about symptoms, diagnosis, causes, risks and treatments and key differences between FTD and Alzheimer's. Objective To assess the impact of new clinical diagnostic criteria for frontotemporal dementia (FTD) syndromes, including primary progressive aphasias (PPA), on prior clinical diagnosis and to explore clinicopathological correlations. The purpose of our review is to determine whether there is sufficient information yet available to justify development of diagnostic criteria for each of these. Incorporating new diagnostic schemas, genetics, and proteinopathy into the evaluation of frontotemporal degeneration, Diagnosis and management of behavioral issues in frontotemporal dementia, Recent advances in the imaging of frontotemporal dementia, An algorithm for genetic testing of frontotemporal lobar degeneration, New approaches to genetic counseling and testing for Alzheimer’s disease and frontotemporal degeneration, Making the diagnosis of frontotemporal lobar degeneration. Screening neuropsychological testing takes several hours and is done by a neuropsychologist (or sometimes under direction of a neuropsychology technician). Brain imaging is indicated in all individuals with symptoms of FTD to rule out structural causes. endobj We evaluated the Lund-Manchester research criteria (LMRC) for frontotemporal dementia (FTD). These are appropriate when there are functional disabilities in communication (speech therapy), mobility (physical therapy) or self-care (occupational therapy). and Bruce Miller, M.D. Definite FTD was diagnosed using the criteria of Rascovsky et al. The final diagnosis was FTD in the variant of PPA. Diagnostic criteria. These are features (see lists 1 through 3) that are not present in all patients, or they may be noted only during one phase of the disease. disinhibition; apathy; lack of empathy; obsessiveness; altered food preferences; executive dysfunction We scored every patient on each LMRC item and compared the two groups. Whereas the latter two present with language disturbances, FTD is characterised by five core clinical criteria, all of which had to be present to make a diagnosis of FTD. Other diseases causing dementia are being increasingly recognised—for example, frontotemporal dementia (FTD). Frontotemporal dementia is much less common than other types of dementia and often has different early symptoms. The early symptoms and the brain image are often the most helpful tools to reach the right diagnosis. The most recent revision of the clinical research criteria was by International Behavioural Variant FTD Criteria Consortium (FTDC) in … Goldman JS, Rademakers R, Huey ED, et al. This study assesses the capability of the NINCDS-ADRDA criteria to accurately distinguish AD from FTD … The Association for Frontotemporal Degeneration these criteria are useful for research, simpler guidelines are needed for general physicians to facilitate recognition of FTD and expedite referral to a specialist centre. 4 The validation process retrospectively reviewed clinical records and compared the sensitivity of proposed and earlier criteria in a multisite sample of patients with pathologically verified FTLD. Electrophysiologic testing is sometimes warranted in patients with possible FTD. Although representing an important first effort at definition, the Lund-Manchester criteria had several limitations. Frontotemporal dementia (FTD) can be hard to diagnose, because it is an uncommon type of dementia and does not cause memory problems at first. The MRI is more sensitive for assessing vascular changes and subtle patterns of atrophy, but it requires an individual to lie still for 15 to 30 minutes. People with frontotemporal dementia (FTD) are often misdiagnosed with Alzheimer’s disease (AD), psychiatric disorders, vascular dementia or Parkinson’s disease. Given the uncommon nature of the condition, and the implications of an incorrect diagnosis, it is reasonable to refer those suspected of having FTD to a specialty center in cognitive disorders. The FTDC simplified the existing diagnostic criteria and attempted to focus on features that best distinguish bvFTD from psychiatric disorders, Alzheimer’s disease and other dementing conditions. endobj The average survival rate after FTD diagnosis is six to eight years. 135 cases were reclassified using the revised diagnostic criteria into behavioural variant (bvFTD), semantic variant PPA (sv-PPA), non-fluent/agrammatic variant PPA (nfv-PPA) and … These patients were compared with 30 with a research diagnosis of Alzheimer's disease (AD). The study by Varma et al is unique because it attempts validation of NINCDS criteria in AD and FTD. These criteria emphasise 3 clinical syndromes, characterised in turn by disorder of personality, social cognition and social conduct, progressive aphasia, or progressive associative agnosia. of criteria in 1998.16 Here the term FTLD was used as an umbrella for three main clinical syndromes: FTD, semantic dementia (SD) and progressive non-fluent aphasia (PNFA). Electromyography is uncomfortable, but may be indicated in cases where concurrent motor neuron disease is suspected.

Whereas the latter two present with language disturbances, FTD is characterised by five core clinical criteria, all of which had to be present to make a diagnosis of FTD. Background: Inter-rater accuracy of the diagnosis of AD has been explored, but there are few accuracy studies for progressive supranuclear palsy (PSP) and frontotemporal lobe dementia (FTD). Confirmation of diagnosis is important for families, and in the advancement of research. Frontotemporal dementias (FTDs) are a group of clinically and neuropathologically heterogeneous neurodegenerative disorders characterized by prominent changes in social behavior and personality or … People with FTD typically first come to the doctor’s office because of: Gradual and steady changes in behavior The earliest changes typically include a disregard for social conventions, impulsivity, apathy, loss of sympathy or empathy, repetitive or compulsive movements, dietary changes and poor insight, planning and assessment. Management of problematic FTD features is challenging, and establishing a working relationship between a primary care physician and a cognitive/behavioral neurologist or psychiatrist, along with a neuropsychologist with expertise in non-pharmacologic modes of behavior management, is strongly advised. In 2011, the International Behavioural Variant FTD Criteria Consortium (FTDC) proposed revised criteria as the 1998 criteria were considered to be too rigid for clinical and research purposes . In some instances, such as when behavioral dyscontrol or marked irritability is present, medications can decrease these features. Research studies and clinical trials are gaining momentum. 1 FTD is thought to be the third most common type of dementia after Alzheimer disease (AD) and dementia with Lewy bodies.FTD is also a common type of early-onset dementia (occurring among … Since the publication of the Strong cr … The criteria for diagnosing post-traumatic stress disorder (PTSD) in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders () are somewhat different than the criteria in the fourth edition.Here are the symptom criteria in the DSM-5. All features must be present to fulfill the criteria for diagnosis. Often this is asymmetrical. For example, behavioral variant frontotemporal dementia (bvFTD) is sometimes misdiagnosed as a mood disorder, such as depression, or as a stroke, especially when there are speech or movement problems. Supportive diagnostic features. Measurement of CSF phospho-tau, total tau and Beta-amyloid can sometimes support the diagnosis of FTD over Alzheimer’s disease. endobj Methods 178 consecutive neuropathologically ascertained cases initially diagnosed with a FTD syndrome were collected through specialist programmes: the Cambridge Brain Bank, UK, and Sydney Brain Bank, Australia. Behavioural variant FTD with definite FTLD Pathology Criterion A and either criterion B or C must be present to meet criteria. Frontotemporal dementia (FTD) refers to a group of disorders caused by progressive nerve cell loss in the brain's frontal lobes. The prodromal phase of dementia with Lewy bodies (DLB) includes (1) mild cognitive impairment (MCI), (2) delirium-onset, and (3) psychiatric-onset presentations. Frontotemporal dementia (FTD) describes a clinical syndrome associated with shrinking of the frontal and temporal anterior lobes of the brain. Despite advances in the understanding of the behavioral variant of frontotemporal dementia, the diagnosis of the syndrome remains challenging. This topic will review the clinical features and diagnosis of the main clinical syndromes of FTD. The core clinical criteria for the diagnosis of mild cognitive impairment (MCI) due to Alzheimer’s disease and Alzheimer’s dementia can be applied to clinical practice immediately. Blood work should be done to exclude alternative causes of cognitive symptoms, including a basic metabolic panel, CBC, RPR, ESR, B12 level and thyroid studies. In this section you will learn the essential facts about FTD. The diagnosis of FTD requires a thorough history, verified by a caregiver, and a neurological examination. Prominent early symptoms include progressive coarsening of personality, social behaviour, self-regulation (of emotions, drives, and behaviour), and language. Neurology 2011 March 15; 76: 1006 – 1014. Frontotemporal dementia is much less common than other types of … These developments should gradually promote enhanced assessment of more patients using advanced tools. A definitive diagnosis of FTD can only be made post-mortem via autopsy of the brain. The prevalence of bvFTD varied between 0.2% and 0.5% at age 70 to 79 years, … Some individuals seek rehabilitation services. Pathological diagnoses included FTLD-tau, … Frontotemporal dementia (FTD) is a neu­rologic disease that affects the frontal and the temporal lobes of the cerebral cortex. This means FTD can be hard for doctors to diagnose as they may not recognise its symptoms as dementia. With single-photon emission CT, we diagnosed 30 patients with FTD. In this section you will learn how you can volunteer your time and talents, raise much-needed funds, and provide your own generous donation. FTD has broader criteria. Historically, these disorders have not been clearly demarcated from AD. As this is an invasive procedure, the value of additional information to be gained should be discussed with patient and family. 1 This disorder is observed most often in people between age 45 to 65, but also can manifest in younger or older persons. Mutations of genes involved in FTD and others dementia were excluded [apolipoprotein E, amyloid precursor protein, presenilin 1 and 2, microtubule-associated protein tau, progranulin (GRN), PARK7]. <> These three sets of diagnostic criteria include different combinations of impairments in social and emotional abilities. With single-photon emission CT, we diagnosed 30 patients with FTD. 1 0 obj The use of multiple testing, however, increased the probability that some statistically significant likelihood ratios … King of Prussia, PA 19406, ©2020 It is recommended that the individual see a genetic counselor first, to be sure they understand the implications of this testing. For bvFTD, consensus clinical criteria (Raskovsky et al., 2011), together with a finding of frontal lobe atrophy on MRI or perhaps a negative amyloid PET scan, can render a diagnosis with great confidence, said Dickerson. The term frontotemporal dementia (FTD) describes a group of neurodegenerative disorders that are characterized by the clinical syndrome of progressive dysfunction in executive functioning, behaviors, and language. OBJECTIVES The diagnosis of Alzheimer’s disease (AD) is now reliant on the use of NINCDS-ADRDA criteria. or email [email protected].

FTDs typically appear in mid-life, with peak onset in the sixth decade. As with other degenerative diseases, FTD presents an insidious onset and progresses over time. Autopsy evaluation of a patient with FTD can be daunting to a general pathologist. As with other degenerative diseases, FTD presents an insidious onset and progresses over time. The early symptoms and the brain image are often the most helpful tools to reach the right diagnosis. A subset (n = 1074) underwent computerized tomography (CT) of the brain. There are no medications which are FDA-approved for the management of FTD-related features. This topic will review the clinical features and diagnosis of the main clinical syndromes of FTD. Two members of AFTD’s Medical Advisory Council – Bradford C. Dickerson, M.D. The diagnosis of FTD requires a thorough history, verified by a caregiver, and a neurological examination. All patients should be screened for obstructive sleep apnea (OSA), as executive dysfunction and behavior changes are common in OSA. They show functional changes in brain glucose metabolism, and are often positive earlier than MRIs. A full neuropsychological testing evaluation should be used to better assess the pattern of cognitive loss in an individual suspected of having FTD and to help rule out psychiatric etiologies for an individual’s symptoms. Some of the major advances reflected in the new criteria include: (i) reduced number of diagnostic features; (ii) no … – presented a Clinicopathological Conference at Massachusetts General Hospital to demonstrate a differential diagnostic process in neurodegenerative disease. Based on the accumulated experience with the 1998 criteria (Mendez and Perryman, 2002; Mendez et al., 2007; Rascovsky et al., 2007a; Piguet et al., 2009), the International Behavioural Variant FTD Criteria Consortium developed revised guidelines for the diagnosis of bvFTD. Overview. 135 cases were reclassified using the revised diagnostic criteria into behavioural variant (bvFTD), semantic variant PPA (sv-PPA), non-fluent/agrammatic variant PPA (nfv-PPA) and logopenic variant PPA (lv-PPA). Criterion C can be positive for possible bvFTD but must be negative for 3 0 obj Frontotemporal dementia is an umbrella term for a group of uncommon brain disorders that primarily affect the frontal and temporal lobes of the brain. Many primary care physicians are uncomfortable making the diagnosis of FTD. When the diagnosis is uncertain, referral to a neurologist with an interest in cognition and behavior and/or a geriatric neuropsychologist is indicated. BvFTD is the most common variant of FTD.   Bring help and support to the next family affected by FTD. FTD has broader criteria. In one series based on 433 cases from an academic memory clinic between 1991 and 2003, specificity was 99% and sensitivity 85% ( Knopman et al ., 2005 ). Rascovsky, K, Hodges, JR, Knopman, D, Mendez, MF, et al. Four years after the FTD diagnosis… We scored every patient on each LMRC item and compared the two groups. Neurology 2013; 80: 496 – 503. Historically, these disorders have not been clearly demarcated from AD. Patients and their families can be pointed to AFTD’s page on the Genetics of FTD for more information.
