EIS is focused on the early detection of, and recovery from, psychosis.  We are a combined NHS and Hafal service for people aged between 14 and 35 living in the Gwent area.  We support those who have either experienced a first episode of psychosis, or those deemed to be ‘at risk’ of developing psychosis.  Our service is offered for up to 3 years from the first appointment.

EIS is community-based and recognises that young people often do not wish to attend clinic settings.   As such, we offer to see people where they feel most comfortable, whether in their own home or in a neutral location such as a coffee shop or outside space.  Our aim is to help young people access the wider community and to achieve their unique goals and aspirations.  We strongly believe that recovery from psychosis is possible.

We offer a multidisciplinary approach based on a young person’s individual needs, including:
•    Education about psychosis and how to stay well
•    Support to access the wider community e.g. work, education, social activities
•    Psychological interventions (talking therapies)
•    Medication prescribing and monitoring
•    Support for family and carers 

If you would like further information about Early Intervention in Psychosis, please refer to the Psychosis Wales website.

What is psychosis?

‘Psychosis’ refers to when a person has trouble working out what’s real and what’s not.  Some things you or others might notice are:
•    Friends and family say you seem different
•    Things seem different, unreal, or surreal
•    Not doing well at school or work
•    Not trusting people
•    Withdrawing from friends, family, and activities
•    Decrease or increase in energy 

Some of the symptoms are:
•    Feeling that there is a plot against you
•    Feeling that your thoughts are being interfered with
•    Seeing or hearing things that others don’t
•    Changes in your mood or feeling more anxious

Who can refer to EIS?

Anyone can refer to EIS, and we even accept self-referrals.  We encourage anyone who has concerns about a young person who may be developing psychosis to call us as soon as possible for a confidential discussion.  Alternatively, email us with your number and we can call you back as soon as possible.

A mental health crisis often means that you no longer feel able to cope or be in control of your situation.

You may feel great emotional distress or anxiety, cannot cope with day-to-day life or work, think about suicide or self-harm, or experience hallucinations and hearing voices.

A crisis can also be the result of an underlying medical condition, such as confusion or delusions caused by an infection, overdose, illicit drugs or intoxication with alcohol. Confusion may also be associated with dementia.

Whether you experience a sudden deterioration of an existing mental health problem or are experiencing problems for the first time, you'll need immediate expert assessment to identify the best course of action and stop you getting worse.
