Terminal Zones of Myelination Dysfunction

Terminal zones of myelination dysfunction refer to abnormalities or impairments in the final stages of myelination, the process of forming the myelin sheath around nerve fibers. Myelin acts as an insulator, allowing for efficient transmission of nerve signals. Dysfunction in these terminal zones can disrupt proper nerve function and lead to various neurological symptoms.

Types:

Terminal zones of myelination dysfunction can manifest in different forms, including:

1. Hypomyelination: Insufficient myelin formation.
2. Demyelination: Loss or damage of existing myelin.
3. Delayed myelination: Slowed or postponed myelin development.

Causes:

There are numerous factors that can contribute to terminal zones of myelination dysfunction, including:

1. Genetic disorders: Such as leukodystrophies.
2. Metabolic disorders: Such as phenylketonuria (PKU).
3. Infections: Such as meningitis or encephalitis.
4. Autoimmune diseases: Such as multiple sclerosis.
5. Trauma: Physical injury to the nervous system.
