Isaacs Syndrome

What is Isaac’s Syndrome?

Isaacs Syndrome is a rare neurological disorder that causes uncontrolled continuous muscle activity, even during sleep. It mostly affects the arms and legs muscles, but it may affect any part of the Body muscles.

Patients with the disease feel stiffness, cramps, and twitching in their muscles. It can also involve your autonomic nervous system, conducting changes in sweating and heart rate.

It’s also known as:

• Continuous muscle fiber activity syndrome.
• Isaacs-Mertens syndrome.
• Neuromyotonia.
• Quantal squander syndrome.

What causes Isaac’s Syndrome?

Isaacs Syndrome can be:

Acquired: This variety of Isaacs syndrome is an autoimmune disease. An autoimmune disease occurs when your immune system strikes normal cells as if they were foreign organisms. Especially, in Isaacs syndrome, approximately 50% of patients have antibodies that target channels that prevent the movement of the electrolyte potassium into and out of your nerve. The motion of potassium in and out of your nerve involves nerve firing.
Hereditary: This variety of Isaac syndrome is genetic. It’s crossed down from one generation to another (inherited).

Risk factors of Isaacs syndrome

It’s likely for anyone to have Isaac syndrome.

Because it can be an inherited disease, you’re a greater chance of Isaac syndrome if you have a parent or sibling who keeps it.

Issac’s syndrome can happen at any age, involving childhood. Generally, onset starts between the ages of 15 and 60. In most patients, symptoms start before the age of 40.

Both males and females can have Isaacs syndrome, but it’s barely more familiar in males.

Acquired Isaacs syndrome is associated with cancer, particularly thymoma.

What are the symptoms of Isaac’s syndrome?

Familiar symptoms of Isaacs syndrome contain:

• muscle twitching
• muscle cramps or spasms
• progressive muscle stiffness
• raised calf muscle mass (muscle hypertrophy)
• extreme sweating
• fast heart rate
• weight loss

If you have Isaacs syndrome, you may see that your muscles twitch, contract, or spasm continuously, particularly the muscles in your arms and legs. This is even the issue while you’re sleeping or under general anesthesia.

You may also see that your muscles have a slowed relaxation reaction. For instance, if you close your eyes tightly for several seconds, they may not unlock right out when you rest them.

Its also been noted that Isaacs syndrome can be associated with the:

• insomnia
• personality and mood alters
• anxiety
• depression

Further symptoms of Issac’s syndrome that are slightly familiar could contain:

• muscle pain
• weakened reflexes
• numbness
• uneven heartbeat
• extreme salivation
• memory loss
• confusion
• hallucinations
• constipation

It’s also feasible for the muscles regulating your capability to breathe, speak, and swallow to be involved, but this is less familiar.

How is Isaacs syndrome diagnosed?

Your healthcare provider or doctor may order examinations to ensure Isaac’s syndrome or rule out further diseases. Tests may contain:

Blood examinations to determine specific antibodies present in up to half of patients with Isaacs syndrome.
Nerve conduction examinations and electromyograms estimate how your muscles and nerves work.
Imaging examinations like a CT scan or MRI.
Occasionally, Isaac’s syndrome is misdiagnosed as another disease, like rippling muscle syndrome, stiff-person syndrome, or cramp-fasciculation syndrome.

How is Isaac syndrome treated?

There’s no treatment for Isaac’s syndrome. Therapy purposes of managing your symptoms and maximizing your daily role. If Isaac’s syndrome is associated with another autoimmune condition or a malignancy, then the therapy of these further conditions is necessary well. For Isaacs syndrome, your healthcare provider or doctor might suggest:

Anticonvulsant (antiseizure) drugs like phenytoin and carbamazepine reduce muscle stiffness, spasms, and pain.
Immunosuppressive drugs like azathioprine and methotrexate.
Intravenous immunoglobulin, a solution including antibodies from donors.
Oral corticosteroids like prednisolone.
Plasma exchange filters toxins and harmful antibodies out of your blood (in people who have irregular antibodies).
