Blood pressure drug holds promise for treating PTSD

Researchers found that clonidine, a common blood pressure medication, can reduce the consolidation of traumatic memories in PTSD patients. By interacting with the adrenergic receptor axis, clonidine interferes with cofilin's ability to form mushroom-shaped dendritic spines, which are essential for memory formation. This suggests that c...
