概括
这项研究发现,患有叶 (TLE) 和抑郁症的患者在与这两种疾病相关的区域表现出常见的大脑温度和胆异常. 这些发现表明和抑郁症的共同神经生物学基础.
科学领域:
- 神经成像是一种神经成像.
- 神经科学是一个神经科学.
- 代谢成像 - 代谢成像
背景情况:
- 和抑郁症经常同时发生,这表明共享的神经生物学途径.
- 叶 (TLE) 和伴随性抑郁症之间的确切关系仍然不太清楚.
- 之前的研究还没有同时研究TLE与抑郁症中的大脑温度和代谢变化.
研究的目的:
- 使用先进的磁共振光谱成像 (MRSI) 和温度计 (MRSI-t) 探索TLE和抑郁症之间的关系.
- 与对照组相比,检查TLE患者患有抑郁症状的脑温度和胆异常.
- 为了确定潜在的共同代谢变化,这两个条件的基础.
主要方法:
- 26名TLE患者和26名对照患者接受了3次MRSI/MRSI-t.
- 胆 (CHO) 与肌酸 (CRE) 的比率 (CHO/CRE) 和大脑温度 (TCRE) 被量化.
- 使用Voxelwise t测试和多式通用关联分析 (mCCA) 来比较组和关联代谢发现.
主要成果:
- 患有TLE的患者表现出比对照组更高的抑郁症状.
- 在TLE患者中观察到左和双边前部区域内CHO/CRE和TCRE的升高.
- 在TLE组的各种大脑区域中,在CHO/CRE和TCRE之间发现了显著的相关性.
结论:
- 大脑温度和胆代谢的异常存在于TLE患者的发作区域和与抑郁症相关的大脑区域.
- 这些发现表明,常见的代谢变化可能是TLE和抑郁症的共同病变的基础.
- 需要进一步的研究来阐明连接TLE和抑郁症的双向神经生物学机制.

Increased Body Temperature
A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in response to an infection or illness.
Methods of reducing fever
The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

Depression: Overview
Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...
