Modafinil has long been hailed as a cognitive enhancer—used by professionals, students, and even military personnel to improve focus and wakefulness. But as its popularity grows, so do concerns around its psychological and emotional impact. One of the most frequently asked questions is: Can Modafinil make you angry or emotionally unstable? Key Takeaways What Is…

Modafinil is a wakefulness-promoting drug increasingly explored for its cognitive-enhancing effects. At the same time, neuroplasticity—the brain’s capacity to adapt structurally and functionally—plays a central role in learning, memory, and neurological recovery. This article investigates how Modafinil influences neuroplasticity, using current scientific literature to evaluate its benefits, risks, and therapeutic potential. Key Takeaways What Is…

Schizophrenia is a severe, chronic mental disorder that affects how a person thinks, feels, and behaves. It is characterized by positive symptoms (e.g., hallucinations, delusions), negative symptoms (e.g., avolition, anhedonia), and cognitive deficits (e.g., impaired memory and attention).
