Hypocalcemia: This condition can cause neuromuscular irritability, leading to tetany, which may manifest as muscle cramps, spasms, or tics. The symptoms can range from mild to severe and can include neurological manifestations such as seizures or altered mental status in extreme cases.

Hyponatremia: Severe hyponatremia can lead to neurological symptoms including confusion, seizures, and in some cases, movement disorders. The rapid correction of sodium levels is crucial to prevent central pontine myelinolysis, which can also present with movement abnormalities.
Hypernatremia: Although less common, severe hypernatremia can cause neurological symptoms due to dehydration of brain cells, potentially leading to seizures, altered mental status, and in rare instances, movement disorders.
Hypomagnesemia: Similar to hypocalcemia, hypomagnesemia can cause neuromuscular irritability and may lead to symptoms such as muscle cramps, weakness, and potentially tics or movement disorders, especially if severe.
Hyperkalemia: While primarily known for its cardiac effects, very high levels of potassium can lead to muscle weakness and, in extreme cases, may contribute to neurological symptoms, though this is less directly associated with tics or movement disorders compared to other electrolyte imbalances.

Hypercalcemia: Although less commonly associated with movement disorders, severe hypercalcemia can lead to confusion, altered mental status, and in rare cases, neurological symptoms that might be mistaken for a movement disorder. The critical aspect of hypercalcemia is its potential to cause life-threatening complications if not promptly addressed.
Electrolyte Imbalance in the Context of Renal Failure: Patients with renal failure are at risk for multiple electrolyte disturbances (e.g., hyperkalemia, hyperphosphatemia, hypocalcemia) that can collectively contribute to neurological symptoms, including potential movement disorders.

Manganese-Induced Parkinsonism: Exposure to high levels of manganese, often occupational, can lead to a parkinsonian syndrome. While not an electrolyte imbalance per se, it's an important consideration in the differential diagnosis of movement disorders with an environmental or toxic etiology.
Other Trace Element Imbalances: Imbalances of trace elements like copper (Wilson's disease) or zinc can lead to neurological symptoms, including movement disorders. These conditions are rare but critical to identify due to their potential for treatment and prevention of long-term neurological damage.
