研究 の 目的:
- 重度のうつ病 (MDD) の青少年における二面性ECTの認知,抗うつ,および抗自殺効果を予測的に評価する.
- 重度の青春期うつ病と自殺傾向に対する治療としてのECTの安全性と有効性を評価する.
主な方法:
- MDDと診断された60人の青少年を対象とした前向きな観察研究 (DSM-5の基準).
- 認知評価 (ケンブリッジ神経心理テスト自動化バッテリー) と臨床結果測定 (HAMD-24, BSI) を基値および治療後1日,2週間,4ヶ月で実施した.
- データ分析は認知機能の変化,うつ病症状の重症度,自殺思考に焦点を当てた.
主要な成果:
- ECTの1日後に空間的および言語的記憶の軽い障害が観察され,2週間以内に完全に回復しました.
