The effect of ACTH on cerebral blood flow in children with intractable epilepsy
Insights
Adrenocorticotropic hormone (ACTH) therapy in children with intractable epilepsy significantly decreased cerebral blood flow velocity. Blood flow returned to normal levels after treatment cessation, suggesting potential impacts on cerebral function.
Area of Science:
- Neurology
- Pediatrics
- Medical Imaging
Background:
- Intractable epilepsy in children presents significant management challenges.
- Adrenocorticotropic hormone (ACTH) is a treatment option for certain pediatric epilepsy syndromes.
- Understanding the physiological effects of ACTH on cerebral circulation is crucial.
Purpose of the Study:
- To evaluate the impact of ACTH therapy on cerebral blood flow in children with intractable epilepsy.
- To assess changes in internal carotid artery blood velocity during and after ACTH treatment.
Main Methods:
- Cerebral blood flow was assessed using ultrasound in 12 children with intractable epilepsy.
- Measurements of average maximal blood velocity (A/L) and end-diastolic blood velocity (d) in the internal carotid artery were taken.
- Data were collected before, during, and after ACTH therapy.
Main Results:
- A significant decrease in mean A/L and d values for both right and left internal carotid arteries was observed during ACTH therapy.
- These cerebral blood flow velocity parameters returned to pre-treatment levels after ACTH cessation.
Conclusions:
- ACTH therapy is associated with a reduction in cerebral blood flow velocity in pediatric patients with intractable epilepsy.
- The observed decrease in cerebral blood flow may influence cerebral function during ACTH treatment.
Abstract:
Cerebral blood flow was assessed by ultrasound in 12 children with intractable epilepsy who were treated with ACTH. The average maximal blood velocity (A/L) and end-diastolic blood velocity (d) of the internal carotid artery were measured, before, during and after ACTH therapy in each subject. The right and left mean A/L and d values were significantly decreased during ACTH therapy, and these values returned to the previous levels after the treatment. Cerebral function in children treated with ACTH may be affected by a decrease in cerebral blood flow.
