OUR Process

RTN Mental Health Solutions provides full diagnostic assessments for neurodiverse conditions. 

We are aware that some NHS waiting times for diagnosis are over two years. We are also aware that private assessments can be out of the financial reach of many people.

We, therefore, decided it was time to create an affordable alternative that is committed to a speedy turnaround time so that clients can get the assistance they need more quickly.

A simple online booking process where we take some basic details and payment.

Filling Out a Form


In order to assist with diagnosis, there are a number of questionnaires that we will be sending out by email for completion. For diagnosis, we need to collect corroborating evidence so we may need to send a questionnaire to a parent/carer, partner, close friend, or teacher.

Mental Health Screening

We are aware that mental health issues are common amongst the neurodiverse community. We have therefore decided to include a mental health assessment. This will help us build a picture of the impact the neurodiverse condition may be having on your mental health and will aid us in being able to make appropriate recommendations for aftercare.
