Melatonin and Dementia: A Comprehensive Overview
Dementia, a collective term for conditions characterized by cognitive decline, affects millions of individuals worldwide. Alzheimer’s disease is the most common form of dementia, and there is a growing interest in the potential role of melatonin in its management.

Understanding Melatonin’s Role
Melatonin is a hormone produced by the pineal gland that regulates sleep-wake cycles. Its levels naturally decline with age, which may contribute to the sleep disturbances often seen in dementia patients. Research has suggested that melatonin supplementation could offer neuroprotective benefits, potentially reducing the risk of developing Alzheimer’s disease and protecting against further degeneration of brain cells1.
Potential Benefits of Melatonin in Dementia
Recent studies have indicated that melatonin may help to protect brain cell health against Alzheimer’s disease. It has been observed that melatonin could induce changes in the brain that prevent or lessen the impact of Alzheimer’s, particularly in the early stages of the disease1. Melatonin’s anti-inflammatory properties may also reduce inflammation, a common feature in progressive stages of Alzheimer’s1.
Clinical Evidence and Research
A systematic review highlighted that disruptions in melatonin levels occur with age and more so in Alzheimer’s compared to age-matched controls. Night-time melatonin levels were found to be lower in the cerebrospinal fluid and blood of Alzheimer’s patients2. However, the research is not entirely conclusive, and more studies are needed to understand the contribution of melatonin disruptions to the pathophysiology of Alzheimer’s disease2.
Safety and Considerations
While melatonin is generally considered safe, some experts advise caution when using it in elderly individuals with dementia. The American Academy of Sleep Medicine does not recommend melatonin for seniors with dementia due to potential safety concerns3. Side effects can include headaches, dizziness, and nausea, and there is no significant evidence that melatonin improves cognition or sleep in those with dementia45.
Conclusion
Melatonin presents a potential avenue for research and treatment in the context of dementia and Alzheimer’s disease. Its ability to regulate sleep and possibly offer neuroprotective effects makes it a compound of interest. However, given the complexity of dementia and the variability of responses to treatment, melatonin should be considered cautiously and as part of a comprehensive management plan. Ongoing research will continue to clarify the role of melatonin in dementia care and help refine treatment strategies.
