Final answer:
Febrile convulsions are investigated using tools such as EEG to record brain activity and CT scans to image the brain for any abnormalities. Neurologists may also evaluate the patient's medical history and perform blood tests for underlying causes. Treatment may involve anticonvulsant medications or surgery in severe cases.
Step-by-step explanation:
Neurological investigations into febrile convulsions primarily aim to determine the cause and extent of the condition. To diagnose and evaluate febrile seizures, neurologists may use electroencephalography (EEG), which records brain activity by attaching electrodes to the scalp. This helps in identifying which regions of the brain are involved in the seizure. For cases with suspected serious conditions such as strokes or tumors, a computerized tomography (CT) scan, a specialized form of X-ray, can visualize the brain for signs of bleeding, tumors, or other anomalies. Additional testing through medical history review or specific blood tests, like those for autoimmune disorders or infections, may be conducted to explore underlying causes such as neurosyphilis or other infectious diseases. Anticonvulsant medications may be prescribed to manage and control seizures, with the possibility of surgery for severe cases.
