F01.5

Clinical Causes: Blockages in blood vessels caused by strokes or transient ischemic attacks (mini-strokes) Small vessel disease leading to narrowing or damage within the small arteries in the brain Atherosclerosis, where fatty deposits build up in arteries reducing blood flow Blood vessel damage from high blood pressure (hypertension) Diabetes-related blood vessel damage Heart conditions such as atrial fibrillation that increase the risk of blood clots

Key Symptoms: Sudden or stepwise worsening of cognitive functions Memory loss that may fluctuate Difficulty concentrating or making decisions Problems with planning or organizing tasks Confusion or disorientation Poor judgment or impaired reasoning Physical symptoms like weakness, paralysis, or difficulty walking (if strokes have occurred) Emotional changes such as depression or apathy

Diagnosis Path: Diagnosis of vascular dementia involves a comprehensive evaluation including medical history, physical examination, neuropsychological testing, and brain imaging studies like MRI or CT scans. These tests help identify infarcts (areas of dead tissue due to lack of blood supply), assess overall brain health, and rule out other causes of cognitive decline. Sometimes, lab tests are performed to check for underlying conditions such as diabetes or high blood pressure that could contribute to the disease.

Treatment Protocols: Controlling blood pressure, blood sugar, and cholesterol levels Medications to improve blood flow or reduce the risk of further strokes Addressing cardiovascular risk factors through lifestyle changes like a healthy diet, regular exercise, and smoking cessation Managing mood and behavioral symptoms with appropriate medications or therapies Supportive therapies such as cognitive rehabilitation and occupational therapy Caregiver support and planning for long-term care needs
