The hallmark symptom of LATE is a progressive memory loss that predominantly affects short-term and episodic memory. [1] This impairment is often severe enough to interfere with daily functioning and usually remains the chief neurologic deficit, unlike other types of dementia in which non-memory cognitive domains and behavioral changes might be noted earlier or more prominently. [1]
The third reason is the "memory self-efficacy," which indicates that older people do not have confidence in their own memory performances, leading to poor consequences. [17] It is known that patients with Alzheimer's disease and patients with semantic dementia both exhibit difficulty in tasks that involve picture naming and category fluency.
Dysautonomia, autonomic failure, or autonomic dysfunction is a condition in which the autonomic nervous system (ANS) does not work properly. This condition may affect the functioning of the heart , bladder , intestines , sweat glands , pupils , and blood vessels.
For example, the tau hypothesis for Alzheimer's proposes that tau protein accumulation results in the breakdown of neuron cytoskeletons, leading to Alzheimer's. [25] Another proposed mechanism for Alzheimer's is related to the accumulation of amyloid beta [ 26 ] in a similar mechanism to the prion propagation of Creutzfeldt-Jakob disease.
As seen in the examples above, although memory does degenerate with age, it is not always classified as a memory disorder. The difference in memory between normal aging and a memory disorder is the amount of beta-amyloid deposits, hippocampal neurofibrillary tangles, or amyloid plaques in the cortex. If there is an increased amount, memory ...
There was a small group of 11 people who met together to talk about late-life mental health needs and the field of geriatrics. This meeting later created the American Association of Geriatric Psychology (AAGP). As time has gone on the small group has turned into a very large group of people dedicated to the well being of the aging population. [6]
Pseudodementia can develop in a wide range of neuropsychiatric disease such as depression, schizophrenia and other psychosis, mania, dissociative disorders, and conversion disorders. The presentations of pseudodementia may mimic organic dementia , but are essentially reversible on treatment and doesn't lead to actual brain degeneration.
There are cultural differences in the prevalence of somatic symptom disorder. For example, somatic symptom disorder and symptoms were found to be significantly more common in Puerto Rico. [48] In addition, the diagnosis is also more prevalent among African Americans and those with less than a high school education or lower socioeconomic status ...
