Dementia, Occurs due to injury or physiological changes in the brain that disrupt communications between neurons, Vascular Dementia, occurs due to damage to the blood vessels in the brain, leading to reduced blood flow and oxygen supply, Lewy Body Dementia, caused by accumulation of abnormal protein deposits called alpha-synuclein in the brain. These deposits disrupt normal brain function, particularly in areas responsible for movement cognition and behavior, Frontotemporal Dementia, caused by the accumulation of abnormal proteins such as tau and TDP-43. This leads to loss of nerve cells, resulting in changes in personality, behavior, language, and emotions. Associated with genetic mutations, Mixed Dementia, Typically involves overlapping pathophysiological changes in the brain, such as vascular damage, accumulation of abnormal proteins or nerve cell loss in specific brain regions, Alzheimer's Disease, Occurs due to a buildup of proteins like beta-amyloid plaques and neurofibrillary tangles in the brain. These cause neuronal damage, resulting in brain shrinkage and impaired communication between neurons. Over time, this leads to cognitive and functional decline, starting often in memory related areas like the hippocampus, Delirium, Occurs due to a lack of oxygen in the brain which can arise from various causes such as metabolic acidosis, medication effects or brain trauma. Develops suddenly over hours to days causing confusion, disorganized thinking and changes in behavior
