概括
双相情感障碍 (BD) 中的帕金森症往往不是由于帕金森病 (PD) 或勒维体病 (LBD). 这项研究表明,它可能是BD本身的一个明显的运动症状,特别是在晚年.
科学领域:
- 神经学 神经学
- 精神病学是一个精神病学.
- 神经成像是一种神经成像.
背景情况:
- 帕金森症是双相情感障碍 (BD) 的常见症状之一.
- 它的原因可能是药物诱导,共发生的帕金森病 (PD),或BD的主要特征.
- 了解BD中帕金森症的病理生理学对于有效的管理至关重要.
研究的目的:
- 在患有双相情感障碍的个体中调查帕金森症的主要病理生理学.
- 在BD中区分帕金森症与帕金森病和勒维体病.
主要方法:
- 招募了16名患有BD和帕金森症的患者.
- 使用了临床评估,多巴胺输送器单光子计算机断层扫描 (DAT-SPECT),心脏123I-metaiodo-benzylguanidine (MIBG) 扫描和MRI形态测量.
- 通过DAT-SPECT和MIBG扫描评估了勒维体疾病 (LBD) 的生物标志物.
主要成果:
- 在BD患者中,帕金森症的发病发生在BD发病10年后,50岁后.
- 在16名患者中,只有4名患者呈现出积极的LBD生物标志物.
- 六名负的LBD生物标志物患者表现出状体吸收减少;大多数患者表现出大脑缩.
- 在四名患者中,有三名患者对利沃多巴治疗没有反应.
结论:
- 在BD中,大多数帕金森症并非归因于PD/LBD.
- 帕金森症在BD中可能代表与疾病相关的真正的晚年运动异常.

Bipolar Disorder
47
Bipolar disorder is a chronic mental health condition marked by significant mood fluctuations, including episodes of mania and depression. Elevated energy levels, heightened mood or irritability, impulsive behavior, reduced sleep needs, rapid speech, racing thoughts, inflated self-esteem, and distractibility characterize mania. Individuals with bipolar disorder often alternate between depressive and manic states, with periods of emotional stability lasting an average of six months to a year.

Parkinson's Disease: Treatment
192
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...

Mania and Antimanic Drugs: Overview
118
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...

Parkinson's Disease: Overview
447
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Psychosis: Goals of Pharmacotherapy
103
Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation.

REM Sleep Behavior Disorder
132
REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.
