Thanks for your question on Health Care Magic. I can understand your concern. Aspiration pneumonia is common in patients with Alzheimer s disease. This is due to impaired consciousness. Best thing for prevention is Ryle s tube insertion. In this, small caliber tube is inserted via nose in the stomach. So that food and water can be given through tube without causing aspiration. Always give food or liquid in sitting position. Never give anything from mouth in supine position. All these will help in prevention of progression of disease. Treatment is dual antibiotic therapy with anaerobic coverage. So make sure that your father is receiving metronidazole or clindamycin. They will fasten the recovery. Hope I have solved your query. I will be happy to help you further. Wishing good health to your father. Thanks.
