Isaac Syndrome

Isaac Syndrome (pronounced eye-zak sin-drome), also known as Neuromyotonia or Peripheral Nerve Hyperexcitability (PNH), is a rare neuromuscular disorder characterized by continuous muscle stiffness, twitching, and delayed muscle relaxation. The syndrome is named after Dr. J. A. Isaac, who first described the condition in 1961.

Etymology

The term "Isaac Syndrome" is derived from the name of Dr. J. A. Isaac, the neurologist who first described the condition. The term "Neuromyotonia" is derived from the Greek words "neuro" (nerve), "myo" (muscle), and "tonia" (tension), which together describe the main symptoms of the disorder.

Symptoms

The main symptoms of Isaac Syndrome include muscle stiffness, twitching, and delayed muscle relaxation. Other symptoms may include excessive sweating, difficulty sleeping, and fatigue. In some cases, the symptoms may be severe enough to interfere with daily activities.

Diagnosis

Diagnosis of Isaac Syndrome is typically based on the patient's symptoms and a physical examination. Additional tests, such as electromyography (EMG) and nerve conduction studies, may be used to confirm the diagnosis.

Treatment

Treatment for Isaac Syndrome primarily involves managing the symptoms. Medications, such as anticonvulsants and beta blockers, may be used to help control muscle stiffness and twitching. In some cases, immunotherapy may be used to help reduce the body's immune response.
