まとめ
アトモクセチンの増強は,注意力障害のある青少年における非自殺自傷 (NSSI) の重症性を有意に低下させた. アトモクセチンは,併発性注意欠陥/多動性障害 (ADHD) とNSSIの青少年に対して有効である可能性が示唆されています.
科学分野:
- 臨床心理学
- 児童・青少年精神科
- 神経科学
背景:
- 非自殺自傷 (NSSI) は,青少年における重大な懸念事項であり,しばしば注意力障害と併発する.
- NSSIの青少年では,注意欠陥/多動性障害 (ADHD) が頻繁に観察され,治療アプローチを複雑にします.
- ADHDの青少年におけるNSSIの既存の治療法は,有効性と増強戦略のさらなる調査を必要としています.
研究 の 目的:
- アトモクセチンを注意力障害の青少年におけるNSSIの増強策として調査するオープンラベル臨床試験のプロトコルを提示する.
- NSSIの重症度および関連する症状の軽減におけるアトモクセチンの有効性に関する予備的な発見を報告する.
- 併発性ADHDの症状と関連する心理的要因に対するアトモクセチンの影響を調査する.
主な方法:
- NSSIとフルまたはサブクリニックのADHDを患った27人の青少年 (年齢13〜18歳) を募集し,4週間前にはADHDの薬を服用していなかった.
- 12週間のアトモクセチンの追加治療で,NSSIの重症度 (プライマリアウトカム) とうつ病,不安,ADHDの症状を含む二次アウトカムを測定した.
- 標準化された診断ツール (DSM-5,Kiddie Schedule for Affective Disorders and Schizophrenia) と結果指標 (自己傷害に関する記述の目録,CDRS,CDI,SCARED,ARS) を利用した.
主要な成果:
- 23人の参加者が試験を完了し,うつ病 (CDRS,CDI) とNSSIの重症度 (それぞれp < 0. 001,p = 0. 031,p = 0. 007) で有意な改善が見られた.
- 全ADHD群では,うつ病 (CDRS) とNSSIの重症度 (p = 0. 017, p = 0. 034) で有意な改善が認められた.
- サブクリニックのADHDグループは,うつ病 (CDRS) の有意な改善と,NSSIの重度の改善の傾向を示した (p = 0. 006,p = 0. 083).
結論:
- アトモクセチンの増強は,注意力障害の青少年,特に併発性ADHDの青少年におけるNSSIの重症度を低下させるのに有望である.
- この集団におけるアトモクセチンの有効な補助治療の役割を支持する.
- これらの予備的な発見を確認し,最適な治療プロトコルを確立するために,より大きな制御試験でのさらなる調査が必要である.

Attention-Deficit/Hyperactivity Disorder
289
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.

Antidepressant Drugs: MAOIs and Other Agents
344
Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Electroconvulsive Therapy
185
Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early...

Modeling in Therapy
145
Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

Mania and Antimanic Drugs: Overview
319
Mania, a psychological condition characterized by elevated mood, increased energy, and reduced sleep need, is part of the bipolar disorder cycle. The exact cause of mania isn't entirely known, but it is thought to be a combination of genetic, environmental, and neurological factors. Bipolar disorder involves alternating manic and depressive episodes. Mood stabilizers like lithium, antipsychotics, and anticonvulsants help manage these episodes. Lithium carbonate is particularly effective as...
