Final answer:
The meta-analysis did not find that abstaining from alcohol reduces the risk of Alzheimer's disease, but identified other modifiable risk factors such as hypertension, depression, and certain dietary choices that can influence the risk. Treatments for managing symptoms of Alzheimer's focus on managing cholinergic neuron activity, while prevention research stresses healthy lifestyle behaviors to mitigate cardiovascular issues associated with the disease.
Step-by-step explanation:
The question addresses findings from a meta-analysis on modifiable risk factors in Alzheimer disease, indicating that abstaining from alcohol did not reduce the risk of the disease. Unlike the incorrect assertion regarding alcohol, the meta-analysis did find that certain factors such as preexisting hypertension, preexisting depression, and dietary habits like coffee consumption can affect the risk of developing Alzheimer's disease. It is important to note that along with genetic predispositions, modifiable risk factors like obesity, poor nutrition, lack of physical activity, tobacco use, and cardiovascular health strongly influence the likelihood of developing not only Alzheimer's disease but also other noninfectious diseases such as cardiovascular diseases and type 2 diabetes.
Management strategies for Alzheimer's disease currently focus on symptom management, with treatments aimed at enhancing acetylcholine neurotransmission or providing psychotherapy and cognitive exercises. Research into prevention emphasizes healthy behaviors that mitigate cardiovascular problems as well. Lifestyle changes, including cessation of smoking, maintaining a nutritious diet, and staying physically and intellectually active, are advocated to reduce the risk of Alzheimer's and other cardiovascular diseases.
