The study was focused on analyzing tau, a protein in the brain that plays a key role in Alzheimer's. In people with the neurological disease, tau proteins undergo chemical changes, forming tangled ...
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]
It's possible that sundowning in dementia patients is caused by a combination of hormonal changes, brain deterioration or damage that has occurred, environmental factors, disruption to a person's ...
Due to the variety of symptoms dementia patients present, it becomes more difficult to assess semantic memory capability especially with regard to musical elements. In order to circumvent the explicit verbal learning tests for dementia, semantic melodic matching is a useful technique for detecting the semantic memory of semantic dementia ...
It is also possible that other brain regions, such as the frontal lobes or the superior colliculus, which are connected to the basal ganglia, underlies attentional deficits in PD patients. Damage to these areas may result in impairment in attentional functioning, and could be a result of deafferentation to these particular underlying areas.
The term young onset dementia is becoming more widely used to avoid the potential confusion between early onset dementia and early stage dementia This term is now used as presenile dementia which is a historical term of people diagnosed with dementia from a younger age of 51 years old. This is caused by an atypical arterioclerosis of the brain.
Binswanger's disease is a type of subcortical vascular dementia caused by white matter atrophy to the brain. However, white matter atrophy alone is not sufficient for this disease; evidence of subcortical dementia is also necessary.
Vascular dementia can be caused by ischemic or hemorrhagic infarcts affecting multiple brain areas, including the anterior cerebral artery territory, the parietal lobes, or the cingulate gyrus. [5] On rare occasion, infarcts in the hippocampus or thalamus are the cause of dementia. [ 12 ]
