What is the disease of brain loss of memory? What is the subject of memory testing

The loss of memory in the brain may be a manifestation of diseases such as Alzheimer's disease, vascular dementia, and sequelae of traumatic brain injury. Memory testing can be done by consulting neurology or psychiatry. The common causes of memory impairment include neurodegenerative diseases, cerebrovascular diseases, brain trauma, psychological factors, nutritional and metabolic abnormalities, etc.

1. Neurology

Neurology mainly diagnoses and treats memory disorders caused by organic lesions in the brain. Alzheimer's disease is the most common neurodegenerative disease, characterized by forgetting about recent events in the early stages, and as the condition progresses, directional impairment and comprehensive cognitive decline may occur. Vascular dementia is often caused by cerebral infarction or cerebral hemorrhage, and memory impairment is often accompanied by executive dysfunction. Encephalitis, brain tumors, and other space occupying lesions may also damage memory related brain regions such as the hippocampus. Neurologists will evaluate the condition through imaging examinations such as head CT and MRI, combined with cognitive scales.

2. Psychiatry

Psychiatry focuses on dealing with psychogenic memory problems. Patients with depression often exhibit pseudo dementia symptoms, accompanied by decreased attention and difficulty in memory retrieval. Post traumatic stress disorder may lead to selective forgetting of traumatic events. Hysterical amnesia is usually manifested as stage memory gaps, which are often related to psychological stress. This type of situation needs to be identified through psychological assessment tools such as the Hamilton Depression Inventory and the Minnesota Multiphasic Personality Inventory, and treatment mainly involves psychological intervention and antidepressant medication.

3. Geriatrics department

provides comprehensive management for memory decline specific to the elderly. Senile forgetfulness belongs to physiological degeneration, but it is important to be alert to the transformation of mild cognitive impairment into dementia. Memory decline caused by vitamin B12 deficiency is more common in elderly people. This department will conduct metabolic indicators such as thyroid function and folate levels, and delay the progression of the disease through nutritional supplementation and cognitive training.

4. rehabilitation Medicine

Rehabilitation Medicine helps rebuild memory function after brain injury. Patients with traumatic brain injury may experience anterograde amnesia, which prevents the formation of new memory traces. Memory impairment after stroke is often accompanied by aphasia or hemiplegia. Rehabilitation therapists will use memory strategy training, external memory aids, and physical therapy such as transcranial magnetic stimulation to improve cognitive function.

5. Endocrinology department

deals with memory problems related to metabolic abnormalities. hypothyroidism can lead to delayed thinking and decreased recent memory, and excessive blood sugar fluctuations may cause damage to the hippocampus. This type of situation requires testing of indicators such as thyroid hormones and glycated hemoglobin. After regulating metabolic status through medication, memory function can be partially restored.

Daily memory maintenance: It is recommended to maintain regular aerobic exercise, such as brisk walking, swimming, etc., which can promote blood circulation in the brain. Eat more foods rich in omega-3 fatty acids, such as deep-sea fish and walnuts, and supplement with moderate amounts of vitamin E and B vitamins. Engaging in cognitive training such as crossword puzzles and Sudoku can help stimulate synaptic connections in the brain while maintaining social activity. If memory impairment continues to worsen, timely medical attention should be sought to investigate the cause and avoid delaying treatment.
