RESUMO
The long-term insulated environment (such as burial after earthquakes, trapped elevators, etc.) can affect emotion by affecting neural plasticity and neurotransmitters, while the bad emotions can further affect normal cognition. Drugs can intervene the emotional problems induced by the insulated environment, such as anxiety and depression, and enhance cognitive ability, the negative influence on brain function induced by the insulated environment can be prevented or alleviated. First, the animal model of brain dysfunction in the insulated environment should be established. The cognitive, learning and memory ability can be evaluated by Morris water maze, Barnes maze, etc. The therapeutic drugs mainly include anti-depression/antianxiety drugs and cognition-improving drugs. Saffron, lavender, passion flower and magnesium ion, have shown good anti-anxiety and anti-depression effects and are suitable for the treatment of emotional problems caused by the insulated environment. Methylphenidate and its analogues, piracetam, hypericum perforatum, and salvia officinalis that can enhance cognition can also be used to prevent and treat cognitive disorders such as inattention and memory decline caused by the insulated environment. Elucidating the mechanism of closed environment and finding more effective drugs can provide a more effective solution to the decline of brain function caused by long-term closed environment..
RESUMO
@#Objective To determine the clinical characteristics of comorbid anxiety and depression after cerebral infarction. Methods All the patients enrolled were divided into post-stroke comorbid anxiety and depression (PSCAD) group (84 cases) and the control group (121 cases). Their condition of smoke, alcohol intake, education background, carotid plaque and brain blood vessels were investigated, and they were evaluated with Hamilton Anxiety Scale (HAMA), Hamilton Depressive Scale (HAMD), Barthel index, and Mini-Mental State Examination (MMSE). Results There was not significant difference in condition of smoke, alcohol intake, education background, carotid plaque and brain blood vessels between these groups （P＞0.05）, but were in total scores and all the factors scores of HAMA and HAMD （P＜0.05）. PSCAD group showed more obvious anxious mood, depressive mood, tension, insomnia, cognitive impairment and autonomic nervous symptoms. Psycho-anxiety, soma-anxiety, despair, guiltiness, decreased interest were also more significant in the PSCAD group. The scores of MMSE and Barthel index were also impaired. Conclusion The cognitive function and daily living ability are worse in the patients with PSCAD. The prominent symptoms includes: anxious mood, depressive mood, tension, insomnia, cognitive impairment, autonomic nervous symptoms, soma-anxiety, despair, guiltiness, decreased interest.
