Motor neuron disease (MND) is a progressive devastating neurodegenerative disease, which universally progresses towards death. Hence, every attempt should be made to find out if there are any treatable conditions, which can mimic MND. Herein, we describe a case of hypercalcaemia due to primary hyperparathyroidism confused as MND and subsequently cured with parathyroid surgery.
- Any patient with neurological disorder should have a screening of all the common electrolytes including calcium as electrolyte imbalance can present with paralysis (e.g. hypokalaemia) to amyotrophic lateral sclerosis (e.g. hypercalcaemia).
- No patient should be stamped as having MND without having a proper work-up of all its differentials as there might be a treatable condition masquerading as MND.
