Living with Psychosis

Interview with Dr Edel Crehan, Psychologist, St Patrick’s Mental Health Services

Psychosis is something many people may have heard of, but it can be greatly misunderstood, despite many of its characteristics having their roots in relatively common human experience.

Clinical psychologist and clinical lead on the Living Through Psychosis programme at St Patrick’s Mental Health Services, Dr Edel Crehan shares her expertise on the condition including its causes and the treatments available at St Patrick’s Mental Health Services.

What is psychosis?

Psychosis has some aspects of anxiety and depression, but the main feature that is unique to psychosis, is that there’s a point at which the person is struggling to determine what’s real and what’s not real, to the point that it begins to pre-occupy them, taking them away from the things that they’re good at, the things they enjoy and their lives in general.

We know that up to 20% of young adults can have psychotic-like experiences, they can have moments or phases in their lives where they might, for example, hear voices or may see things that other people can’t see. We know that up to 8% of the population may have psychosis at any point in their lives, however people who suffer from psychosis to a degree that requires treatment, amount to between 1 and 3% of the population.

Is psychosis an umbrella term – what kinds of conditions does it cover?

Psychosis is now emerging as the commonly used term, technically it is an umbrella term that can bring a person into lots of different diagnoses. When a person enters a mental health service, the team will try to figure out, based on their experiences what category the person falls into, e.g. schizophrenia (a term that’s very much falling away from clinical practice now).

Psychosis can be an indicator that maybe there’s a bipolar affective disorder condition emerging. For some people, it’s an indicator that there’s a severe depression or adjustment issues happening. For women who have had a pregnancy, it may be an indicator that there’s some postnatal depression emerging. Psychosis can indicate any of those.

What is the experience of having psychosis, and is it something people who’ve never had the condition can relate to?

We now know that psychosis is actually a very common human experience. There is now a very large emerging evidence that psychosis or psychotic-like experiences are actually very common human experiences.

We know, for example, that people who have an interest, or pre-disposition to spirituality will often talk about hearing voices or seeing images, experiencing it in quite a positive way. We know that people actively seek to use mind-altering drugs so that they can see, hear and feel unusual experiences. We know that psychotic-like experiences can happen as a very natural part of grief. Often when you speak to someone who is in the throes of grief, they will say that they think they saw their loved one, or they think they heard their loved one. We know that that’s a psychotic-like experience – but it’s not psychosis, it’s a very common human experience.

We also now know that people who have endured severe abuse or neglect, be it emotional, physical or sexual, quite often the way that the mind processes that through flashbacks, can resemble psychotic experiences where the person doesn’t know if they’re reliving something, questioning is it real, is it not real. It’s not surprising that if someone has had a very difficult childhood or had very challenging things happen in their lives, they may have a vulnerability to a mental health difficulty.

What are some of the causes of psychosis?

Broadly the causes are a combination of biological, psychological and social factors.

Biological causes

  • If someone has a parent or a first degree relative who has a mental health difficulty, that leaves them slightly more vulnerable than their peers, so the risk of psychosis is greater if there’s already a family history.
  • Some people, through no fault of their own, can have a vulnerability to having too much cortisol in their system which can leave them getting stressed more easily. This increased sensitivity to stress can make people more vulnerable to changes that may warrant professional help.

Psychological causes

  • We now know that someone who is depressed or anxious can have an increased vulnerability to developing psychosis. That’s not to say that everyone, or even most, will it’s simply a risk factor.
  • Some people can have conditions like social phobia or social anxiety. At the heart of these conditions is a fear of other people and they can lead to psychosis emerging in some cases.

Social

  • If you’re a young adult and you’re experimenting with drugs, some of your friends might do the same and never have any symptoms of psychosis. You, however, might be the one person who experiments or becomes reliant on drugs and alongside that you may develop symptoms of psychosis.

The strongest links are between cannabis use and the emergence of psychosis. Even if you have changed your lifestyle and have stopped using cannabis, for some people that is when their vulnerability to psychosis emerges. This is linked to the fact that they no longer have the soothing effects of cannabis and may start to struggle with paranoia or anxiety.

  • We now know in research, and this may not be commonly known, that if you were bullied to an extent that really damaged your self-esteem, destroyed your confidence or isolated you, there is a greater risk of psychosis. This is because the world no longer feels safe, and ultimately psychosis is a condition of fear that becomes so distressing, so preoccupying, so overwhelming that you can no longer trust your friends, you can no longer trust your own mind.

Given those range of possible causes, how do people and those close to them, recognise what’s happening and access help?

Quite often with depression and anxiety, and individual themselves with realise, “I’m feeling stressed, I’m feeling anxious, I’m down all the time, I don’t like it, I need to get some help”. With psychosis it’s quite different. It’s very rare that someone will recognise that they’ve early signs and symptoms of psychosis and they need to get help. Instead what often happens is a very secretive, personal process where it could be rumbling on for weeks, months and in some cases, tragically, years. Slowly a loved one, a parent, a friend will notice the person’s performance is going down, they’re spending a lot of time on their own, they’re not enjoying their hobbies anymore. They bring their concerns to the person and often, the person pushes that help away, or is too scared, too ashamed or too confused to engage with it.

In many cases loved ones have to try multiple times to convince the person to come with them to the GP perhaps for information, and to get them to a point where they start to see, actually there is a problem here and I need help. The technical term for that is insight.

What treatments are available for people with psychosis?

Here at St Patrick’s Mental Health Services, we run the Living Through Psychosis programme over eight weeks. In general, we have six to eight people at a time in that group, from all walks of life, all ages. We get to know them as people first, who just so happen to have this issue of psychosis.

For some people they get to the end of the eight weeks and they feel like they have the skills to go to the shops, meet their friends, get back to day to day life and do the things that matter to them. Others will realise over the course of the programme that a particular instance of bullying or a life event had a massive impact on them and explains why they’re in their threat system a lot of the time. Often those people will choose to go into individual therapy or other psychological intervention to address the issue. Then there are some people who complete the programme and decide that they would like to explore medication options.

For some people, they will do they eight-week programme but feel that they need more tools to help manage their psychosis. There’s now a level 2 Living Through Psychosis programme that brings in the idea of compassion. A significant aspect of compassion is courage and when you have a condition of fear and you struggle with high levels of threat, one of the things that balances that out, is courage – and it can be taught.

People who live with psychosis often worry about their minds, questioning if they’re mad or bad. One of the things that balances that out is wisdom, beginning to learn that we all get tricked by our brains from time to time, we all get stuck in worry loops about what people think of us, the future etc. Wisdom can really help to offset these worries. We now know that it’s possible to live with psychosis, you can go back to college, you can go back to work, you can speak about it. Absolutely.
