Neurocognitive disorders - Answer>> delirium and dementia
Dementia - Answer>> -a group of symptoms that mainly affects
memory, cognition and social interactions, and the ability to do
everyday tasks.
-Symptoms start gradually often with no clear beginning, and are
usually permanent.
-Most dementias are caused by neurodegenerative diseases, most
commonly Alzheimer's disease, Lewy body dementia and
frontotemporal dementia
• clumps of abnormal proteins to build up inside neurons,
damaging them, and causing them to slowly degenerate and die -
vascular dementia is another common cause of progressive dementia
• brain damage occurs when the blood supply to the neurons is
reduced or blocked, again causing them to malfunction or die -
Cognitive Symptoms: Difficulty with complex tasks, Difficulty planning
and organizing, Loss of coordination
-Psychological symptoms: Personality changes, Inappropriate
behaviour, Paranoia, Fear, anxiety, anger or depression.

neurons
• tangles - tau protein inside neurons (neurofibrillary tangles)
Alzheimer's disease brain progression - Answer>> -Plaques &
tangles usually start forming and spread from the cortex
• earliest areas affected temporal lobe (learning & memory)
• as it spreads goes to frontal lobe (thinking & planning)
