Neurodegenerative conditions, including Alzheimer's disease, Parkinson's disease, and Huntington's disease, result in a substantial health problem for the elderly, marked by ongoing neuronal degeneration and a deterioration in mental faculties. These disorders are frequently linked to oxidative stress, problems with mitochondria, and persistent inflammation in the brain, which worsen neuronal damage. The neurohormone melatonin, primarily secreted by the pineal gland, has gained recognition as a promising therapeutic agent due to its antioxidant, anti-inflammatory, and neuroprotective effects. Melatonin's functions extend beyond its regulation of circadian rhythms, as research has demonstrated its ability to remove free radicals, improve mitochondrial performance, and adjust immune system responses, ultimately reducing the progression of neurodegenerative disease. Research findings from preclinical and clinical trials imply that taking melatonin supplements could lead to improved cognitive abilities, slower disease progression, and an overall better quality of life for elderly individuals suffering from neurodegenerative conditions. The mechanisms through which melatonin acts, the best dosage, and its long-term effectiveness are still being researched. This review underscores the potential benefits of melatonin as a supplementary treatment for neurodegenerative disorders in older adults, stressing the necessity for additional studies to confirm its efficacy and standardize its use in treatment plans.
