Which investigations should be considered in a patient presenting with new-onset dystonia?

Investigations for new-onset dystonia:

• In adults presenting with suspected dystonia, routine cervical imaging is not recommended to evaluate the condition.
• Referral for neurological assessment is advised to confirm diagnosis and consider treatment options such as botulinum toxin therapy.
• Consider medication history carefully, as antipsychotic and antiemetic drugs can trigger or worsen dystonia.
• In children with sudden-onset dystonia, urgent neurological assessment is recommended.

Overall, the initial approach focuses on clinical assessment and specialist referral rather than routine imaging or laboratory investigations in primary care.

Summary: No routine imaging or specific laboratory tests are recommended initially; instead, refer for specialist neurological assessment to establish diagnosis and management.
