Influence of Covid 19 on cognition impairment with Type II diabetes

Due to the increase in life expectancy and population growth over 65 years, cognitive impairment (CI) is gradually increasing. Because of many changes in the human brain that occur with aging, cognitive decline usually worsens with age. The number of neurons, dendrites, synapses, receptors, glial components, and critical neurotransmitters (norepinephrine, dopamine, acetylcholine) diminishes every year after age 50 (by 0.1–0.2 percent). As a result, the brain's volume, metabolism, and perfusion decrease, and an average age-related cognitive decline emerge
