Alzheimer’s disease can be tested by neuropsychological examination, in addition to physical and neurological examination, laboratory tests, EEG and other aspects of testing.
1. Neuropsychological examination: In order to evaluate the patient’s application ability, speech function, memory ability, attention, executive function, etc., neuropsychological tests using tools such as scales are required. Commonly used tools include Simple Mental Status Scale, Clinical Dementia Rating Scale, Neuropsychiatric Questionnaire and so on.
2. Physical and neurological examination: In the early stage, patients need to be comprehensively assessed for orientation, speech function, attention, perception and muscle tone, coordination, balance and other items for examination and observation.
3. Laboratory examination: Alzheimer’s disease patients also need to check blood biochemistry, blood routine, urine routine, cerebrospinal fluid examination and other laboratory tests to distinguish and exclude other diseases.
4. Electroencephalography (EEG): Patients with Alzheimer’s disease often have changes in the EEG, and in the early stage of the disease, the EEG changes are mainly the slowing down of the alpha rhythm and the reduction of wave amplitude. In a few patients, the alpha wave is obviously reduced or even completely disappeared. In the late stage, a wider range of theta activity can gradually appear, and in the late stage, it is manifested as diffuse slow wave.
If Alzheimer’s disease is suspected, it is necessary to consult the hospital in time and actively diagnose and treat the disease to avoid delay.
