To tell if your autistic child might have schizophrenia, look for sudden, significant changes from their typical autistic behavior, like severe social withdrawal, disorganized speech that becomes truly incomprehensible (not just autistic communication style), or signs of psychosis (hearing/seeing things, bizarre beliefs, paranoia), especially if they show new disinterest in daily life or hygiene, requiring immediate professional evaluation by a child psychiatrist.
It was subsequently pointed out that individuals with autism share many of the negative features of schizophrenia, such as social withdrawal and communication deficiencies, but do not share the positive symptoms, mainly involving hallucinations and delusions (Rumsey, Andreasen, & Rapaport, 1986).
The U.S. Food and Drug Administration (FDA) has approved two medicines for the treatment of autism-related irritability. They are risperidone (Risperdal) and aripiprazole (Abilify). They belong to a class of drugs known as atypical antipsychotics.
Early warning signs of schizophrenia in children may include:
It can cause a range of different psychological symptoms, including hallucinations and delusions. Being autistic and having schizophrenia is thought to be rare, but the research and evidence is very limited.
Around 90% of autism cases are attributed to genetic factors, meaning autism is highly heritable, with many different genes contributing, rather than a single cause, often interacting with environmental influences during early brain development, though specific environmental factors don't cause it but can increase risk. Twin studies show strong genetic links, with concordance rates between 60-90% in identical twins, and research points to complex interactions of many genes and prenatal/perinatal factors.
A few disorders have some of the same symptoms as schizophrenia (schizophrenia spectrum disorders), including:
Schizophrenia changes how a person thinks and behaves.
The first signs can be hard to identify as they often develop during the teenage years. Symptoms such as becoming socially withdrawn and unresponsive or changes in sleeping patterns can be mistaken for an adolescent "phase".
The following symptoms and behaviors can occur in children or adolescents with schizophrenia: seeing things and hearing voices which are not real (hallucinations) odd and eccentric behavior and/or speech. unusual or bizarre thoughts and ideas.
In most people with schizophrenia, symptoms generally start in the mid- to late 20s, though it can start later, up to the mid-30s. Schizophrenia is considered early onset when it starts before the age of 18. Onset of schizophrenia in children younger than age 13 is extremely rare.
The "6-second rule" for autism is a communication strategy where a speaker pauses for about six seconds after asking a question or giving information, giving the autistic person extra time to process it without feeling rushed, which helps reduce anxiety and allows for a more thoughtful response, reducing frustration for both parties. Instead of repeating or rephrasing, which can be confusing, you wait, and if needed, repeat the exact same words after the pause.
Ritalin is a well-known stimulant medication often prescribed for individuals with autism. It helps to manage hyperactivity and impulsivity while enhancing focus and attention. Many parents find that Ritalin can significantly improve their child's ability to concentrate and participate in daily activities.
There is not just one cause of ASD. Many different factors have been identified that may make a child more likely to have ASD, including environmental, biologic, and genetic factors.
Severity is rated by a quantitative assessment of the primary symptoms of psychosis, including delusions, hallucinations, disorganized speech, abnormal psychomotor behavior, and negative symptoms.
Sometimes, autistic individuals without psychotic symptoms are misdiagnosed with schizophrenia. This results from certain measures used in testing for hallucinations and delusions that can mislead autistic respondents.
Risk of psychosis across ages among ASD people
A recent meta-analysis focused on the few studies (n = 4) that included subjects with autism in their high risk for psychosis cohorts (CHR-P), reporting a pooled prevalence of ASD as high as 11% (range between 2.5 and 40%, Vaquerizo-Serrano et al., 2022).
Several other childhood disorders such as autism spectrum disorder, post-traumatic stress disorder, anxiety disorders, and major depressive disorder with psychotic features have symptoms that overlap with COS, and misdiagnosis is common.
The "25 rule" (or "rule of quarters") in schizophrenia suggests that outcomes fall into four roughly equal groups: 25% recover fully, 25% improve significantly with some ongoing support, 25% improve somewhat but need considerable help, and 25% have a poor outcome with chronic illness or suicide risk, highlighting the varied nature of schizophrenia's long-term course, though some sources use a "rule of thirds" with similar proportions for different outcomes.
Early warning signs are: Trouble telling dreams from reality (distorted view of reality) Confused thinking, such as confusing TV with reality. Detailed and bizarre thoughts and ideas.
delusions, such as a belief that a person is being poisoned. hallucinations, such as hearing a voice that issues orders. disorganized speech, such as logic that is difficult for others to understand. catatonic behavior, ranging from coma-like inactivity to hyperactivity.
The first phase is referred to as the prodrome (or prodromal) phase. During this period the person starts to experience changes in themselves, but have not yet started experiencing clear-cut psychotic symptoms.
Many of schizophrenia's better-known symptoms are in the positive symptom category, including: Hallucinations. These occur when a person's senses — vision, hearing, touch or smell — experience things that do not exist. Hallucinations and delusions may be referred to as psychotic symptoms or psychosis.
Youth with autism have been found to be three to six times more likely to develop schizophrenia than their peers without autism.
Symptoms may include:
Unsurprisingly, there have been cases in which early cognitive symptoms of a primary psychotic disorder were mistakenly attributed to the more vogue ADHD with stimulant prescription exacerbating (or even causing) positive symptoms (Karatekin et al., 2010; Shyu et al., 2015; Studerus et al., 2018).
