Webb14 feb. 2024 · The researchers concluded that the apparent decreases in delta and theta waves on the EEG are an indicator of brain dysfunctions associated with mental health conditions. Another study by Bell (2012) used EEG to investigate the working memory performance of fifty 8-month-old infants. WebbThe effects of a 5-day treatment with rivastigmine on the resting EEG power spectrum were studied in 15 mildly to moderately ill Alzheimer patients. In these patients, beta power was positively correlated with cognitive performance and negatively correlated with functional impairment. Rivastigmine produced a decrease in delta and theta power with n
