[Abnormal movements and internal medicine pathologies].

Abnormal movements can signal underlying internal medicine conditions. Prior research has shown that hyperkinesias often arise from metabolic or endocrine imbalances. However, the specific associations between these movements and systemic pathologies remain underexplored. No prior work had resolved the full range of internal medicine causes for acute chorea, dystonia, tremors, and akathisia. This gap motivated a closer examination of known clinical associations. The challenge lies in distinguishing neurological symptoms from those caused by systemic factors. Differentiating between drug-induced and idiopathic movement disorders is critical for accurate diagnosis. This paper aims to clarify the internal medicine pathologies linked to various hyperkinetic syndromes.

This paper seeks to identify the internal medicine conditions associated with abnormal movements. The specific problem is the lack of a comprehensive overview of systemic causes of hyperkinesias. The motivation stems from the need to improve diagnostic accuracy in clinical settings. By reviewing known associations, the authors aim to guide clinicians in identifying treatable causes. The study focuses on acute chorea, dystonia, tremors, and akathisia. Each movement disorder is linked to specific metabolic, endocrine, or pharmacological factors. The goal is to highlight the importance of considering internal medicine pathologies in differential diagnosis. This approach may help reduce misdiagnosis and unnecessary interventions.

The authors conducted a literature review to identify known associations between hyperkinesias and internal medicine conditions. They analyzed case reports and clinical studies on acute chorea, dystonia, tremors, and akathisia. The focus was on metabolic, endocrine, and pharmacological causes of these movement disorders. They examined the role of non-ketotic hyperglycemia, lupus, and antiphospholipid syndrome in acute chorea. The review also included the impact of neuroleptics, metoclopramide, and oral contraceptives on dystonic syndromes. Tremor associations were linked to drug and hormone use. The study considered pregnancy and iron deficiency anemia in akathisia. The synthesis of findings aimed to clarify the systemic origins of these neurological symptoms.

Acute chorea is associated with non-ketotic hyperglycemia, lupus, and antiphospholipid syndrome. It may also appear with endocrinopathies, pregnancy, and psychostimulant use. Acute dystonia is linked to old-generation neuroleptics, metoclopramide, and oral contraceptives. It must be distinguished from tetany caused by hyper- or hypocalcemia. Tremors are found in association with various drugs and hormones. Akathisia is classically linked to chronic neuroleptic use. Restless legs syndrome is associated with iron deficiency anemia, pregnancy, and polyneuropathies. It may also occur during benzodiazepine or opiate withdrawal.

The authors propose that hyperkinesias may signal underlying internal medicine conditions. They suggest that acute chorea may be linked to non-ketotic hyperglycemia and antiphospholipid syndrome. They propose that acute dystonia may be caused by neuroleptics or metoclopramide. They suggest that tremors may be drug- or hormone-related. They propose that akathisia may be associated with chronic neuroleptic use or withdrawal. They suggest that restless legs may be linked to iron deficiency or pregnancy. They propose that clinicians should consider systemic factors when diagnosing movement disorders. They suggest that a multidisciplinary approach may improve diagnostic accuracy.
