Dr Soumitra Datta Hello, I’m Soumitra Datta, Consultant Child Psychiatrist. Today we would be talking on “Management of Psychosis in Children and Adolescents.” This talk would be in two parts, so go through it sequentially, and hopefully, by the end of it, your understanding of managing psychosis in this age group would be somewhat better.
I don’t have any conflict of interest to declare. I was part of the Cochrane Schizophrenia Group, the Cochrane Collaboration, for the last several years and we would talk about the reviews we have produced. That’s the only conflict of interest I can talk of. We will touch upon, you know, the presentation of psychosis in children and adolescents, the differential diagnosis in this age group and what is the evidence base for managing this group of children who have developed psychosis? And how do you wrap it all together when you apply this evidence base to your daily clinical setting?
Now, psychosis in a youth, you know, is diagnosed based on a diagnostic criteria, just like adults. So, children and adolescents may have positive psychotic symptoms, like delusions, hallucinations, they may have negative symptoms, or they might have behaviours, which are disorganised. We do need to distinguish formal thought disorders in this age group, with specific language disorders, because children are growing, and they acquire more than one language in their lifespan. And, you know, while they’re learning, they might, you know, sort of, express certain ideas, which is different from adults.
Misdiagnosis of psychosis in adolescents is quite common. So, you have to be careful, while making a diagnosis, and we will talk about that a little bit. Children who develop schizophrenia has – you know, research has shown that they have premorbid problems with, you know, verbal reasonings, memory and attention span. And so, if you go back and take history of those children you have made a diagnosis of psychosis, you might be able to spot things which were, sort of, warning signs prior to the confirmatory diagnosis of psychosis. There is also, typically, a cognitive decline after the psychosis have stabilised. So, there might be impact of the disease on their overall functioning of the adolescent. However, this is not routine. Many patients with psychosis might do well with treatment.
Now, how do you make a differential diagnosis, which we are talking about? So, you know, a neurotypical child may have overactive imagination, they may have vivid fantasies and that’s being a child. And the other thing, which you have to consider, is that some adolescents might be at a high-risk state. So, you know, if there is a family history of psychosis, there is a recent deterioration in the functioning, say the school functioning, there might be paranoid thoughts, some degree of social impairment. However, these symptoms do not only, you know, conform to the diagnosis of diagnos – psychosis, or it might be that, you know, there are transient symptoms or attenuated symptoms of psychosis. So, this is what we call – is a high-risk state.
Sometimes, and again, in adolescents, it’s not uncommon for children who have juvenile-onset obsessive compulsive disorder, and they may have obsessional thinking related to symmetry, or they may have an obsessive thought in terms of something terrible will happen. And Clinicians should be careful not to make the mistake of labelling this as a, you know, paranoid delusion. Autistic spectrum conditions, lack of social reciprocity, some idiosyncratic beliefs, these are again – you know, they may have some similarities with a young person developing psychosis. However, in psychosis, usually there is an onset, acute onset, or – you know, whereas in autistic spectrum examination, it’s a longstanding pattern.
You can have adolescents who develop bipolar illnesses, mania, with psychosis, so florid delusions, elaborate thoughts, rapid speech, as opposed to, you know, paucity of speech, and some children and adolescents might actually develop psychosis, or even schizophrenia. So that this could be – the onset could be slow, insidious, or it could be, you know, acute. There is usually a change in functioning when a young person develops a psychotic illness.
So, you know, to summarise, you have to go through the entire spectrum of a neurotypical child, to an anxiety disorder, like obsessive compulsive disorder, somebody with a high-risk state, or having developed psychosis, like mania and schizophrenia. So, this is – these are the differentials that you would need to consider while managing a patient – a young person. Now, a mental high-risk state, if you see the recent meta-analysis, it does shay – say that, you know, “At five-year follow-up, one in six youth diagnosed with at-risk mental state,” which the authors say, “ARMS” had transitioned to psychosis, but they did not find evidence that this resk – risk was related to the ARMS diagnosis, as opposed to just a sampling or a recruitment, you know, strategy reflecting on the results. So, you do need to be careful while dealing with this very fragile group of children and putting a label.
Now, psychosis in children and adolescents, you know, the other thing, which you need to consider, is normal children can have hallucinations, which are not part of a psychiatric syndrome. A child may be bereaved or having grief, they may have funeral hallucinations. There could be acute and transient psychosis, often related to a stress, which does not progress to a lifelong psychotic condition. There might be prodromal symptoms, which could be anxiety symptoms, but later on, develops into psychosis, so you need to follow-up the child over time.
There could be, very rarely, actual childhood onset schizophrenia. It’s very, very rare, in the sense that one in 10,000 children develop childhood onset schizophrenia, which is very different from adult onset schizophrenia, where the prevalence in 100. So, you might be a Child Psychiatrist, practising your entire life and not come across a person with childhood onset schizophrenia. Now, in adolescents with psychosis, the picture changes, because, you know, one fifth of all adults with psychosis actually have the onset of illness in their adolescence. However, you need to, as I mentioned earlier, be mindful of that this could be the first episode of a psychotic bipolar disorder. And also, you know, don’t misdiagnose schizophrenia with other disorders, which I have been talking about, like OCD.
Now, in childhood onset schizophrenia, so childhood means, you know, less than 13-years-of-age, it’s not adequately studied because it’s very rare, as I have been mentioning. However, the diagnostic validity is more or less established for, you know, below 13, but below six it’s not very well established. The framework which we use, as Psychiatrists, is same as adults, like positive, negative and cognitive decline. There are prodromal symptoms, often, there could be an acute phase, there could be a recovery phase, or there would be residual symptoms. The outcomes, you know, there could be some moderate to severe impairment in some children. So, you need to be, you know, educating the family and working with the families, instilling them hope, at the same time, being realistic about how they need to engage with the Mental Health Services for a considerable length of time.
All children with suspected schizophrenia, if they have these following features, should be evaluated for a medical condition. You know, if there is, sort of, a history of substance misuse, so, you know, is this cannabis induced psychosis? Or, you know, if there is a family history of an illness, which presents with psychotic symptoms, or if there is symptoms suggestive of PTSD, with a history of trauma, abuse. So, these are things, which you need to be mindful about.
So, while you’re doing physical examination of a child, if there is organic signs, like focal neurological deficits, seizures, you know, further evaluation, brain imaging, etc., might be necessary. Referral to an appropriate specialist, like a Neurologist, when appropriate, should be done. History of medical illnesses, as I mentioned, that, you know, if there is a history of the man – child having a medical illness, like porphyria, which may have, you know, psychotic symptoms, that needs to be looked into. If there is a family history of similar illness, that again, you know, that condition needs to be evaluated, say Wilson’s disease, something like that. But, you know, by and large, these are rare. Be mindful that you do need to do a physical examination for children and adolescents with psychosis. It will not be causal, but at least you would be treating the child in a holistic way.
So, while we, you know, sort of, end the – this part of our discussion, we do need to end with the fact that, you know, antipsychotic medications are the primary treatment for schizophrenia spectrum disorders in children and adolescents. However, we are treating a child here, so we need to be, you know, treating the child with the psychological and social components in mind. Children, almost always, are in a family, so engaging with the parents, getting their consent, explaining what we are treating their children for, allaying their anxieties. So, these would go a long way in, sort of, engaging the family and having a better outcome for the child.
So, I would like to conclude that, you know, diagnosis of psychosis needs careful consideration of other differential diagnosis. You need to have regular follow-up, be open to emerging symptoms and psychopathology, which might happen over the course of your follow-up. Psycho-educate and, you know, when appropriate, you have to start medications, but engage the child and the family together. Thank you.
