Multi-infarct dementia (MID) is a prevalent cause of dementia in older adults. In the current report, we look at a small acute haematoma in the right parietal lobe, a small infarct in the right thalamus and occipital lobe, a multiple chronic infarct in both cerebral hemispheres and a mild subdural hygroma over bilateral cerebral convexity caused by Diabetes and Coronary Artery Disease. A 86-year-old man patient was diagnosed with Multi-infarct dementia, Acute ICH in the right parietal lobe, Chronic subdural hygroma and Vitamin D3 insufficiency. The patient was administered with Diuretics, Anti-convulsants, Anti-Depressants, Cholinesterase Inhibitors, Antibiotics, Psychostimulants, Nootropics and Anti-hyperlipidemic drugs. Early identification, proper Blood Pressure (BP) management and therapy are all required for the treatment of Multi- Infarct Dementia.
