Thanks for your query. The usual causes of poor concentration in academic activities would include specific learning disorders, lack of interest in the subject per se, substance use, thyroid
disorders and mild variants of mood disorders
. Healthy diet, daily exercises, scheduling of your daily activities, maintaining a proper sleep-wake cycle will aid in reducing your problems. If the difficulty still persists kindly contact a psychiatrist
for a through assessment before deciding on any management plan.
