Final answer:
Marie-Charcot-Tooth (MCT) disease is a genetic disorder affecting the peripheral nerves, causing muscle weakness and sensory loss in the limbs. Diagnostic tests include nerve conduction studies and dural nerve biopsy. Treatment focuses on stabilizing the ankles through surgical fusion and individuals with MCT disease can have a normal lifespan and remain mobile.
Step-by-step explanation:
Marie-Charcot-Tooth (MCT) Disease:
Marie-Charcot-Tooth (MCT) disease, also known as Charcot-Marie-Tooth disease, is a genetic disorder that affects the peripheral nerves and causes muscle weakness and sensory loss in the limbs. It is characterized by decreased motor and sensory nerve velocity, which can be confirmed through diagnostic tests such as nerve conduction studies. In some cases, a dural nerve biopsy may also be performed.
Treatment and Prognosis:
The main aim of treatment for MCT disease is to stabilize the ankles, usually through surgical fusion, in order to improve mobility and prevent further deformities. Despite the challenges posed by this condition, individuals with MCT disease can lead a relatively normal lifespan and most remain ambulatory.
