Cognitive health is the ability to clearly think, learn, and remember. Functions such as motor skills, emotional responses, and sensory responses indicate a resilience to neuropathological damage.
Genetic, environmental, and lifestyle factors are all thought to influence cognition and health. Some of these factors may contribute to a decline in thinking skills and the ability to perform everyday tasks.
Environmental and lifestyle factors which patients can control are risk factors for health problems. These can include heart disease, diabetes, stroke, and depression, and brain injuries. Studies have shown and agreed on risk factors which can contribute to cognitive decline. These include some medicines, or improper use of them, lack of physical activity, poor diet, and smoking. They can also include drinking too much alcohol, sleep problems, little social activity or being alone most of the time.
