Bifrontal versus bitemporal electroconvulsive therapy in severe manic patients.

Area of Science:

• Psychiatry
• Neuroscience
• Clinical Trials

Background:

• Severe mania requires effective and safe treatment options.
• Electroconvulsive therapy (ECT) is a recognized treatment for severe mania.
• Different electrode placements and dosages of ECT may influence efficacy and cognitive side effects.

Purpose of the Study:

• To compare the efficacy and safety of moderate-dose bifrontal (BF) versus low-dose bitemporal (BT) electroconvulsive therapy (ECT) in patients with severe mania.

Main Methods:

• A parallel, double-blind, randomized clinical trial was conducted.
• Twenty-eight patients with severe mania were randomly assigned to receive either moderate-dose BF-ECT (n=14) or low-dose BT-ECT (n=14).
• Primary outcome measures included the Mini-Mental State Examination (MMSE) for cognition and the Young Mania Rating Scale (YMRS) for mania severity.

Main Results:

• No significant differences in baseline MMSE or YMRS scores were observed between the groups.
• Both BF-ECT and BT-ECT groups showed significant improvements in YMRS scores.
• The BF-ECT group demonstrated significantly higher MMSE scores compared to the BT-ECT group after the sixth and final ECT sessions, indicating better cognitive function.

Conclusions:

• Moderate-dose bifrontal ECT is as effective as bitemporal ECT in treating severe mania.
• Bifrontal ECT is associated with fewer cognitive side effects compared to bitemporal ECT.
• This suggests that moderate-dose BF-ECT may be a preferable treatment option for patients with severe mania, balancing efficacy with cognitive safety.
