Symptoms of Monomelic Amyotrophy
Monomelic Amyotrophy is characterized by a gradual onset of weakness in one or both sides of the body, accompanied by a loss of muscle mass and function in the hands. This weakness progressively worsens over a period of approximately three years before reaching a stable state. Interestingly, while deep tendon reflexes remain unaffected, individuals with this condition may exhibit the absence of upper motor neuron signs. Additionally, some individuals may experience cold paresis, which refers to a heightened weakness sensation when exposed to cold temperatures.
Neuralgic Amyotrophy: Causes and Symptoms
Neuralgic amyotrophy primarily affects the peripheral nerves in the upper limbs and is more commonly observed in young men in their early twenties. Although not a chronic condition, it can recur in some individuals. The exact cause or trigger of neuralgic amyotrophy is often unknown, but in certain cases, it may occur shortly after upper respiratory tract infections, vaccinations, childbirth, or invasive medical procedures.
