Alzheimer's is understood as a common memory loss disease in the elderly. The origin of Alzheimer's disease comes from the brain cells responsible for memory and some other functions begin to die.

Diagnosis of Alzheimer's disease is based on a combination of clinical signs and laboratory tests. Early diagnosis and treatment can help slow the progression of the disease and allow families to make better decisions about their future plans.

Previous studies have shown a link between higher intake of the omega-3 fatty acid DHA and a reduced risk of Alzheimer's disease. Conversely, lower serum DHA levels have been associated with amyloid plaque accumulation in the brain, lower cognitive function, and smaller hippocampal volume.

Recent research has shown marked reductions in the incidence and prevalence of dementia, improvements that appear to be linked to earlier investments at the population level, such as better community education and improvements in conditions related to vascular disease, further emphasizing the need for these early prevention measures, the researchers said.
