Androgen Therapy in Neurodegenerative Diseases

Area of Science:

• Neurobiology
• Neurology
• Endocrinology

Background:

• Neurodegenerative diseases involve neuron loss and dysfunction.
• Androgens exhibit neuroprotective and axonal regeneration properties in animal models.
• Neuronal androgen receptors suggest therapeutic potential.

Purpose of the Study:

• To review the potential of androgen therapy for neurodegenerative diseases.
• To summarize existing evidence on androgen effects in AD, PD, MS, and ALS.
• To highlight the need for further clinical investigation.

Main Methods:

• Review of existing studies on androgen therapy in neurodegenerative diseases.
• Analysis of effects on inflammation, amyloid-β, cognition, remyelination, and motoneuron recovery.
• Assessment of clinical data availability and limitations.

Main Results:

• Androgen therapy reduced inflammation, amyloid-β, and cognitive decline in Alzheimer disease.
• Improvements in remyelination were observed in multiple sclerosis.
• Variable results were noted in Parkinson disease.
• Androgen administration promoted motoneuron recovery and axonal regeneration in ALS.

Conclusions:

• Androgen therapy demonstrates potential neuroprotective and regenerative effects across various neurodegenerative conditions.
• Limited clinical data exists, necessitating large-scale human trials.
• Androgen therapy is a safe, low-cost option warranting further investigation.
