In addition to screening for common conditions such as bipolar disorder, anxiety and depression in all patients, he also emphasizes the importance of screening for conditions that can manifest in childhood (such as ADHD, Autism) as well as first-episode psychosis in young adults.

From the initial visit and onward, Dr. Islam prioritizes a collaborative effort with his patients (and at times their families).
