Can als be misdiagnosed?

AUSTIN – Lack of upper motor neuron signs on examination, presence of sensory symptoms, and absence of tongue fasciculations are common causes of amyotrophic lateral sclerosis (ALS) misdiagnosis, according to an investigation presented at the annual meeting of the American Association of Neuromuscular and

Can thyroid disease mimic ALS?

Amyotrophic lateral sclerosis (ALS), a progressive neurological disorder, can be challenging to diagnose because its obvious symptoms are common to other neurological conditions. A poorly working thyroid can cause myopathy, or muscle disease, leading to the muscular weakness and cramps also experienced by ALS patients.

Can MND be misdiagnosed?

The misdiagnosis of MND (particularly of the ALS phenotype), is uncommon. Atypical presentations, particularly of focal onset and with pure LMN or UMN signs, present a more difficult diagnostic challenge, although perhaps reassuringly, treatable mimics are rare.

Can a pinched nerve mimic ALS?

ALS symptoms usually start with painless weakness developing in a hand or foot and can be mistaken for more common problems, such as carpal tunnel syndrome or a pinched nerve. The muscle weakness slowly gets worse. Other symptoms and signs include: Muscle stiffness and wasting.

  3. MRI.
  4. Blood and urine tests.
  5. Spinal tap (lumbar puncture).
  6. Muscle biopsy.

Is there a definitive test for ALS?

Is Hyperreflexia a symptom of ALS?
