Diabetic amyotrophy

Hello everyone!

Today, I will be talking about diabetic amyotrophy.

Diabetic amyotrophy has a lot of names!

It is also known as Bruns-Garland syndrome, diabetic myelopathy, proximal diabetic neuropathy, diabetic polyradiculopathy, diabetic motor neuropathy, diabetic radiculoplexopathy, diabetic lumbosacral plexopathy, and diabetic LRPN.

Diabetic amyotrophy typically occurs in patients with type 2 diabetes mellitus. The traditional features include the acute, asymmetric, focal onset of pain followed by weakness involving the proximal leg, with associated autonomic failure and weight loss. Progression occurs over months and is followed by partial recovery in most patients.

The diagnosis of diabetic amyotrophy is mainly based upon the presence of suggestive clinical features in a patient with known or newly diagnosed diabetes mellitus. Appropriate laboratory investigations, particularly electrodiagnostic studies, and neuroimaging in select patients, are useful to exclude other peripheral and central nervous system etiologies as a cause of the neurologic symptoms and signs.

No treatments are proven to be effective for diabetic amyotrophy or for idiopathic LRPN.

PS: Distal symmetric sensorimotor polyneuropathy is the most common type of diabetic neuropathy - it is characterized by a progressive loss of distal sensation correlating with loss of sensory axons, followed, in severe cases, by motor weakness and motor axonal loss. Classic "stocking-glove" sensory loss is typical in this disorder.
