Given the popularity of contact sports, research on the prevalence and development of CTE has grown in recent years. One study examining the brains of professional football players […]
Overview Primary progressive aphasia (PPA) is a neurodegenerative disorder characterized by progressive language decline. It is the less common type of frontotemporal dementia (FTD), which accounts for 20-40% of cases. The other type of FTD is called behavioral variant of frontotemporal dementia, which affects personality and behavior. There are three subtypes of primary progressive aphasia, […]
Overview Dementia with Lewy bodies (DLB) is a neurodegenerative disorder (or dementia) characterized by physical (resemble Parkinson’s disease), psychiatric (visual hallucinations), and cognitive (fluctuating cognition) symptoms. It is the second most common type of age-related dementia, preceded by Alzheimer’s disease. Initially, an individual may be diagnosed with mild cognitive impairment when deficits have not significantly […]
Overview Behavioral variant of frontotemporal dementia (bvFTD) is a neurodegenerative disorder characterized by prominent changes in personality and behavior. It is the more common type of frontotemporal dementia (FTD), which accounts for 70% of cases. The other type of FTD is called primary progressive aphasia, which affects language abilities. Initially, an individual with bvFTD may […]
Alzheimer’s disease (AD) is a neurodegenerative disorder (or dementia) notable for prominent memory loss and other cognitive impairments. It is the most common form of age-related dementias. Alzheimer’s disease is diagnosed through neuropsychological assessment, in which the individual’s cognitive abilities are tested using standardized administration of paper-and-pencil tests, and neuroimaging. Initially, an individual may be […]
