The intellectual impairment in multi-infarct dementia sometimes involves only certain specific, limited cognitive functions, such as difficulties with calculation and naming. The general reasoning and judgment can remain intact for a considerable period of time, and they are often able to detect these impairments and actively seek medical attention or make efforts to compensate for them, hence the name “mesh-like dementia”. So, what are the screening methods for reticular dementia? Here is a brief introduction. The general reasoning and judgment can remain intact for a considerable period of time, and they can often detect these disorders and take the initiative to seek medical help or try to make up for them. 2. The electroencephalogram of retinobulbar dementia often shows obvious abnormalities; 3. 4, CT scan shows low density areas and limited ventricular enlargement; 5, magnetic resonance imaging can show luminal infarct foci. Our reticular dementia and cerebrovascular diseases are very closely related, so we should pay attention to our own health from now on in order to prevent us from getting Alzheimer’s disease in our old age. Patients are advised to go to the hospital as soon as the symptoms of reticular dementia appear to achieve early detection, early diagnosis and early treatment to avoid delaying the disease and causing irreversible consequences.
