Mental Health Glossary
Whether you’re looking for clarity about your own mental health, supporting someone you care about, or simply want to understand psychological conditions better, this resource is for everyone—children, teens, and adults. The aim is to provide gentle, straightforward explanations for common mental health and neurodevelopmental conditions, so you feel empowered and less alone on your journey.
-
First point of contact: If you have concerns about your own or someone else’s mental health, your GP or family doctor is the best place to start. They can listen, advise, and refer you to appropriate support services.
-
Psychologist vs. Psychiatrist: Psychologists offer talking therapies and behavioral support. Psychiatrists are medical doctors who diagnose conditions and, when needed, prescribe medication. You might see one or both depending on your needs.
-
Support in Workplaces and Communities: Many workplaces, universities, and community centers now have mental health first aiders, well-being coordinators, or peer supporters. They can provide guidance, signposting, and sometimes crisis support.
-
School and College Mental Health: For students or young people, professional help can often start with a school counselor, educational psychologist, or student well-being team.
This glossary isn’t exhaustive, but it covers many of the most common mental health, neurodevelopmental, and behavioral challenges that people of all ages may face. If you notice symptoms that worry you, seeking early advice is always a wise and caring step.
