Overview
Prevention of dementia is the attempt to avoid developing dementia. Although no cure for dementia is available, there are many ways to decrease the risk of acquiring dementia in the first place, including both lifestyle changes and medication. UK National Institute for Health and Care Excellence recommends lifestyle and behavioral interventions (stopping smoking, reducing alcohol consumption, increased physical activity, eating healthily, maintaining a healthy weight) to decrease the risk of frailty and dementia
Primary prevention
Lifestyle
Exercise programs improve physical functioning or at least slow the progression of functional decline in patients with dementia. Exercise programs do not appear to improve cognitive functioning in adults with dementia [1]
Behavioral Disturbance
Recognition and treatment of delusions, hallucinations, depression, agitation, aggression, and sleep disturbances are important aspects of the care of patients with dementia.
Nutrition
Decreased sense of smell is also common in dementia patients and can manifest itself as poor appetite and weight loss. Provision of high-calorie supplements can help with weight gain in patients with dementia. Ongoing eating problems are very common in advanced dementia patients.
Mental Activity
Use it or Lose it" might be applied to the brain when it comes to dementia. Cognitive stimulation programs benefit cognition, but that studies were of variable quality and further research is indicated[2]
Physical Activity
Exercise programs may improve physical functioning or at least slow the progression of functional decline in patients. Exercise programs do not appear to improve cognitive functioning in adults with dementia.[1] Studies showed that Physical therapy and occupational therapy significantly improved motor skills compared with controls.[3]
Risk factor control
Controlling the risk factors for stroke, cardiovascular disease, and dementia represent an important strategy for decreasing the incidence of dementia.[4]
Patients whose vascular risk factors were treated had a slower decline in MMSE scores compared with those whose vascular risk factors were not treated. [5]
Alcohol
Advise patients to limit alcohol consumption i.e , one drink per sitting and avoid after-dinner alcohol completely because of detrimental effects on sleep.
