Abstract:
Anticonvulsants have been used for the treatment of impulsive aggression since the 1980s. A 50-year-old man suffered from irritability and agitation after developing a right ipsilateral frontal lobe infarction as a result of Moyamoya disease; these symptoms caused difficulties with his working and interpersonal relationships. The patient had been treated using multiple benzodiazepine agents for 2 years but his symptoms had not improved. However, after treatment with carbamazepine (CBZ; 200 mg) was begun, the patient's irritability and agitation gradually decreased. The efficacy of CBZ treatment in this patient suggests a method for controlling benzodiazepine-resistant impulsive aggression.
Insights
Carbamazepine effectively treated impulsive aggression and agitation in a patient resistant to benzodiazepines. This finding suggests carbamazepine as a potential treatment for similar benzodiazepine-resistant cases.
Area of Science:
- Neurology
- Neuroscience
- Pharmacology
Background:
- Anticonvulsants have been explored for treating impulsive aggression since the 1980s.
- Moyamoya disease can lead to neurological complications, including frontal lobe infarction.
- Frontal lobe infarction can manifest as irritability and agitation, impacting social and occupational functioning.
Observation:
- A 50-year-old male patient presented with persistent irritability and agitation following a right ipsilateral frontal lobe infarction due to Moyamoya disease.
- The patient's symptoms were refractory to two years of treatment with multiple benzodiazepine agents.
- Conventional treatments failed to alleviate the patient's behavioral disturbances.
Findings:
- Initiation of carbamazepine (CBZ) treatment at 200 mg resulted in a gradual reduction of the patient's irritability and agitation.
- Carbamazepine demonstrated efficacy in managing symptoms that were unresponsive to benzodiazepines.
- The patient experienced significant improvement in behavioral symptoms with carbamazepine therapy.
Implications:
- Carbamazepine may offer a viable therapeutic option for benzodiazepine-resistant impulsive aggression.
- This case highlights the potential of carbamazepine in managing aggression secondary to neurological conditions.
- Further research into carbamazepine for refractory aggression is warranted, particularly in post-stroke or neurovascular disease populations.
