Alzheimer's disease: diagnosis and treatment, errors in patient management

Abstract

Alzheimer's disease (AD) is the most common degenerative disease of the brain leading to dementia. AD is the most common cause of disability among age-related diseases. The diagnosis of AD is based on clinical findings and is confirmed by the presence of positive biological markers of the disease, which reflect the pathological formation of beta-amyloid and tau protein in the brain. Magnetic resonance imaging of the brain shows brain atrophy in AD and helps to rule out other diseases. Psychosocial and behavioral approaches form the basis for the treatment of patients with AD; cognitive training in combination with regular physical exercise is recommended. Acetylcholinesterase inhibitors and the glutamate receptor blocker memantine are used as drugs that improve the cognitive functions of patients with AD. Dispersible forms of memantine are used to treat dysphagia in patients with AD. The efficacy and safety of pathogenetic therapy aimed at eliminating cerebral beta-amyloid by passive immunization is under discussion. Unfortunately, AD is rarely diagnosed in our country; doctors are not sufficiently informed about the diagnosis and modern treatment methods of AD. Many AD patients are observed with the misdiagnosis of chronic cerebrovascular disease and do not receive effective therapy. A clinical observation of a patient with early-onset AD is presented, reflecting typical errors in patient management. Issues for optimizing the management of AD patients are discussed.
