Dementia, delirium, and depression are not part of normal aging but are organic brain syndromes that often are reversible. Thus, it is imperative that primary care physicians carefully look for a reversible cause in a patient with one of these disorders. Even an irreversible condition, such as Alzheimer's disease, can be effectively treated with drugs that are carefully chosen to minimize serious side effects. Patients with cognitive impairment deserve to be treated with dignity, and every effort should be made to maintain the highest level of function possible.
痴呆、谵妄和抑郁并非正常衰老的一部分，而是往往可逆转的器质性脑综合征。因此，初级保健医生必须仔细寻找患有这些病症之一的患者的可逆病因。即使是像阿尔茨海默病这样的不可逆病症，也可以通过精心选择的药物进行有效治疗，以尽量减少严重的副作用。认知障碍患者值得得到有尊严的治疗，应尽一切努力维持尽可能高的功能水平。
