A Doença de Parkinson (DP) apresenta-se na senescência, limitando o movimento e progredindo para demência, sendo assim a segunda doença neurodegenerativa no mundo relacionada a idade. Desse modo, esta revisão bibliográfica tem como objetivo reunir informações relevantes sobre a DP para direcionar novas abordagens científicas que favorecerão à aplicação clínica, e assim, a qualidade de vida dos pacientes da PD. Foram selecionados e analisados 80 estudos publicados nos últimos 20 anos em base de dados com descritores indexados. O resultado observado direciona para a compreensão de teorias causais, sintomas motores e não-motores, diagnóstico e tratamento. Concluiu-se que o estudo norteia, a partir das informações levantadas, novos estudos experimentais para a melhora da qualidade de vida de pacientes da DP.
Bromazepam emulates the inhibitory effect of the neurotransmitter gamma-aminobutyric acid (GABA) and can lead to impaired visuomotor performance. However, few studies have evaluated its effects on cortical coupling in target shooting activities. The present study aimed to analyze the acute effects of bromazepam administration in a target shooting task and the EEG theta rhythm coherence between frontal, temporal, and motor cortical areas in four shooting preparation periods. Thus, a double blind, crossover study was conducted with 30 subjects under two conditions: bromazepam (6mg) and placebo, with electroencephalographic analysis to simultaneously study the theta rhythm coherence in frontal, temporal, and motor cortex in a target shooting task; and the possible interferences of bromazepam administration. Subjects in the bromazepam group showed lower performance on the task compared to placebo (p=0.001). In addition, our analysis showed decreased coherence between regions in the same hemisphere, increased theta rhythm coherence in interhemispheric regions in frontal, temporal and motor cortex at different intervals in the preparation preceding the shooting (p=0.001). The use of bromazepam may influence task execution, possibly due to neurochemical modulation, during decision making, developing shooting preparation strategies, as well as interfering with the flow of information at the level of attention during task execution.
