Blood glucose, or blood sugar, is sugar in the bloodstream that easily passes the blood-brain barrier and it is an immediate source of energy for the cells. Our brain uses a large amount of energy, and is dependent on blood glucose as its source of energy. Hypoglycemia, reduced blood sugar level has been found to induce central nervous system symptoms such as tiredness, confusion, and slowed mental function. Various Researchers have reported reduced ability and processing speed for verbal events during the hypoglycemic state. Studies have been carried out at the level of retrieving words with a specific letter and also for lexical retrieval. The associations between the verbal fluency tasks and the blood glucose levels have contradicting results from the literature. Present study aimed at evaluating differences of hypoglycemic and euglycemic state in healthy individuals on verbal fluency task. A group of 20 healthy adults (2 males and 18 females) between 18-25 years were subdivided into experimental and control group with 10 in each group. Gender and linguistic equivalence was confirmed for both the groups. All the subjects underwent a simple letter fluency task, a complex letter fluency task and lexical fluency task with category switching in English. Results of the study revealed presence of deficits on complex letter fluency tasks by young healthy individuals in a hypoglycemic state which projects a need for insight into the association of blood glucose levels and cognitive linguistic processing. However, the results for simple letter fluency and category switching did not reach a statistically significant difference between the two groups.
