Synaptopathies: synaptic dysfunction in neurological disorders - A review from students to students

Area of Science:

• Neuroscience
• Cell Biology
• Pathology

Background:

• Synapses are crucial for neuronal communication, regulating behavior, and maintaining brain function.
• Perturbations in synaptic function are increasingly recognized as key factors in various brain disorders.
• The concept of synaptopathies unifies diseases characterized by shared synaptic defects.

Purpose of the Study:

• To review fundamental synapse structure and function.
• To critically examine the role of aberrant synapse physiology in neurodevelopmental and neurodegenerative disorders.
• To discuss the implications of classifying synapse-related diseases under the term 'synaptopathies'.

Main Methods:

• Literature review and synthesis of current research.
• Discussion of basic concepts in synaptic structure and function.
• Critical analysis of evidence linking synaptic dysfunction to specific neurological diseases.

Main Results:

• Synaptic dysfunction is implicated in a spectrum of disorders, including autism, epilepsy, Alzheimer's, and Parkinson's disease.
• Aberrant synapse physiology is a common pathogenic feature across diverse neurological conditions.
• The 'synaptopathies' concept provides a unifying framework for understanding these diseases.

Conclusions:

• Understanding shared mechanisms and unique differences in synaptic dysfunction is vital for developing targeted therapies.
• The 'synaptopathies' classification may facilitate novel, synapse-based therapeutic interventions for neurological and neuropsychiatric disorders.
• Further research into disease-associated synaptic dysfunction can advance brain health strategies.
