Background: Thiamin or vitamin b1 is a therapy that has been widely used in neurology cases such as alcohol-induced encephalopathy and neuropathy. Thiamin has the ability to penetrate the blood brain barrier so that it is expected to be used as an additional therapy in stroke cases. Stroke is currently an emergency neurology case that causes high mortality and disability. Among the causes is because damage to large areas of the brain will cause the release of neurotransmitters such as glutamate which has excitotoxicity effects to the brain when excessive. Method: This study used animal models of carotid artery occlusion stroke. Divided into 4 groups: control, thiamin dose of 100mg/kg, Thiamin 200mg/kg, and 400mg/kg. Serum glutamate was collected on day 7 post-action. Then evaluated by ELISA method. Results: There was a significant difference in the form of a decrease in the average serum glutamate level between the control and the sample that received a dose of thiamine 200mg/kg and 400mg/kg. Conclusion: High-dose thiamine may be considered as an additional therapy in cases of carotid artery occlusion model stroke.

Memory and learning is negatively affected by many factors. Alzheimer{\textquoteright}s disease is a progressive and irreversible neurological disorder that occurs gradually, a sickness that is increasingly common, and multiple scientific articles suggest that essential oils improve memory and learning and are useful in the treatment of various neurodegenerative diseases, including Alzheimer{\textquoteright}s disease. This review aims to conduct a critical collection of current information on research into both memory and learning impairment, as well as essential oils that are able to avoid this neurodegenerative disease. Currently, different animal models have been useful for the study of neurodegenerative problems that alter memory and learning, experimental pharmacological, genetic and toxicological models that can simulate specific cognitive deficit syndromes. In addition, research in this review show several essential oil compounds that present positive results in animal studies, but still lack human clinical trials. Therefore, the assessment of the safety and efficacy of these phytochemical compounds in diseases that cause memory impairment and learning, remain a promising area for future research.
