No Cognitive Impairment (NCI). Subjective Cognitive Impairment (SCI). Mild Cognitive Impairment (MCI). Dementia.. What is the usual cause of impaired mental functioning in older adults?Cognitive impairment in older adults has a variety of possible causes, including medication side effects; metabolic and/or endocrine derangements; delirium due to illness (such as a urinary tract or COVID-19 infection); depression; and dementia, with Alzheimer's dementia being most common.
Which of the following individuals is at the greatest risk of developing Alzheimer's disease?Age. Age is the biggest risk factor for Alzheimer's. It mainly affects people over 65. Above this age, a person's risk of developing Alzheimer's disease doubles about every five years.
