Aging brain and dementia- Alzheimer’s Disease
Aging changes all parts of body including the brain: Certain parts of brain shrink, especially prefrontal cortex and hippocampus, both important to learning, memory, planning, and other complex mental activities. Changes in neurons and neurotransmitters affect communication between neurons. In certain brain regions, communication between neurons reduces because white matter (insulation-covered axons) is degraded or lost. Brain’s blood vessels aging causes reduction in blood flow as arteries narrows with age.
Memory loss triggers:
Memory deficits increases by stress, stroke and or decreased brain blood flow, medical conditions like electrolyte imbalance, hypoglycemia, liver failure, addictions, B12 vitamin deficiency, poor social support, infections, multiorgan failure, hearing or visual deficits.
