Thyrotoxic neuropathy (Basedow's paraplegia)

Area of Science:

• Neurology
• Endocrinology

Background:

• Hyperthyroidism, a condition of excess thyroid hormones, can present with various neurological complications.
• Polyneuropathy, characterized by widespread nerve damage, is a rare but recognized manifestation of severe thyrotoxicosis.

Observation:

• A patient with severe thyrotoxicosis developed a specific polyneuropathy impacting leg muscles, termed Basedow's paraplegia.
• Electrophysiological studies and muscle biopsy confirmed the presence and nature of the polyneuropathy.

Findings:

• The patient's leg muscle involvement was diagnosed as a neuropathic or nerve-mediated process.
• This neurological complication was distinct from a potential thyrotoxic myopathy.

Implications:

• This case highlights the importance of considering polyneuropathy in patients with severe hyperthyroidism.
• Understanding this association aids in accurate diagnosis and management of neurological complications in thyrotoxicosis.
