The endocannabinoid system: a putative role in neurodegenerative diseases

Area of Science:

• Neuroscience
• Pharmacology

Background:

• Research into D9-tetrahydrocannabinol (THC) has spurred exploration of the endocannabinoid system.
• The endocannabinoid system's role in neurological conditions is an active area of scientific investigation.

Purpose of the Study:

• To review the endocannabinoid system's function in neurodegenerative diseases.
• To synthesize current scientific literature on this topic.

Main Methods:

• Critical analysis of recent scientific literature.
• Qualitative synthesis of significant research articles.

Main Results:

• Endocannabinoids modulate synaptic plasticity and cognitive, motor, sensory, and affective processes in the central nervous system.
• Endocannabinoids exert neuroprotective and pro-homeostatic effects in neurodegenerative and neuroinflammatory diseases via CB1 and CB2 receptors.
• Endocannabinoid system hypofunction or dysregulation is implicated in multiple sclerosis, ALS, Huntington's, Parkinson's, and Alzheimer's diseases.

Conclusions:

• The endocannabinoid system's significant role suggests promising therapeutic developments.
• Further research may lead to novel treatments in psychiatry and neurology targeting the endocannabinoid system.
