In contrast to major depression, dementia is a progressive neurodegenerative syndrome involving a pervasive impairment of higher cortical functions resulting from widespread brain pathology. [ 7 ] A significant overlap in cognitive and neuropsychological dysfunction in dementia and pseudodementia patients increases the difficulty in diagnosis.
A hyperfixation can also come be related to executive functioning issues, Adler says, which can make time management and decision-making challenging — especially during times of stress.
Sundowning is often a symptom that happens after someone is diagnosed with dementia or a dementia-related disease, but it can also be an early sign of mental decline itself. “There are changes ...

A new study shows that a depression diagnosis earlier in adulthood increases the risk of developing dementia later. Now, researchers want to know why. A new study finds a strong link between ...
In subcortical dementia, there is targeted damage to regions lying under the cortex. The pathological process that result in subcortical dementia shows neuronal changes that involve primarily the thalamus , basal ganglia , and rostral brain-stem nuclei and mostly, some projections in the white matter from these regions to the cortex, with ...
One other specific age related factor noted in Popescu et al. is a decrease in estrogen as one ages could adversely affect the breakdown of the blood-brain barrier and create a sensitivity to neurodegeneration. [14] As pointed out earlier, dementia is a broad category of memory impairments most commonly associated with ageing.
