Risk factors for Alzheimer's disease Early reviews identified over 20 risk factors associated with Alzheimer's disease (AD) including age, familial inheritance, exposure to aluminium, traumatic brain injury (TBI), and associated co-morbidities such as vascular disease and infection. In the light of recent evidence, this review reconsid …

Plaques and tangles damage the healthy brain cells around them. The damaged cells die, and the brain shrinks. These changes cause the symptoms of Alzheimer’s, such as memory loss, speech problems, confusion, and mood swings. Brain cells affected by the disease also make lower amounts of the chemicals called neurotransmitters ...
