Yes. The report includes practical recommendations tailored to your needs. These may relate to work, study, daily life and wider support, so you have clearer guidance on possible next steps.
Dr Shyamal Mashru and Dr Maja Elia from ADHD Health Clinic explore how ADHD can present differently in women, and why it is so often missed or misdiagnosed.
ADHD Health Clinic is not a crisis service. If you are experiencing a medical emergency, call 999 immediately. For urgent medical help that is not life-threatening, contact NHS 111.
For non-urgent enquiries during working hours, you can reach our admin team at admin@adhdhealthclinic.co.uk.
We offer a free 10-minute call to discuss your needs and help match you with the most suitable psychiatrist for your assessment.
Symptoms often manifest differently in individuals and can have a significant impact on various aspects of life.
“Dr Mashru is an extremely personable doctor, and it is clear that he takes a genuine interest in the wellbeing and comfort of his patients. I am of a naturally nervous disposition, but during my interactions with Dr Mashru I felt extremely reassured and comfortable at all times, and felt welcomed to share my thoughts, concerns, questions and experiences in order for us to determine the best possible course of care together.”
