Duration Of Mood Episodes
A person who has schizoaffective disorder is likely to experience severe mood symptoms accounting for more than half of the total duration of illness.
On the other hand, a person who has schizophrenia may also experience mood episodes, but the total duration of the mood symptoms is brief compared to the duration of the psychotic symptoms.
Symptoms Associated With Asd Are Often Misdiagnosed
A study concluded that adult psychiatric service patients with autism are often misdiagnosed. The authors suggest that adult psychiatrists may not be familiar with the diagnosis of ASD. They conclude by saying the high comorbidity rate between schizophrenia and autism may be related to shared neurobiology, but they dont exclude the possibility that arbitrary restrictions imposed by the current diagnostic system also play a part.
Diagnostics have obviously improved in the last decade since this study was published but it does emphasize the importance of diagnostic criteria. If an autistic childs behavior changes suddenly, or if they seem increasingly disconnected from reality, parents should ensure the medical professional they choose to consult with is familiar with both autism and other mental disorders.
While most pediatricians are well versed in areas of mental health, childhood onset schizophrenia in a young patient with autism may require a doctor with diagnostic expertise in developmental disorders and childhood onset schizophrenia.
Hallucinations In Schizophrenia And Aspergers Syndrome
Hallucinations occur in a number of psychiatric conditions including the general population and psychiatric disorders. Lewis et al. notes that first rank symptoms have been found to vary from a minority of patients to very high rates in both schizophrenia and in other psychiatric disorders, depending on the population being studied. Nevertheless Schneiders first rank symptoms of schizophrenia which include audible thoughts voices commenting on patients actions thought withdrawal thought insertion thought broadcasting made impulses of drives made volitional acts delusional perception. This profile in my clinical experience does separate schizophrenia from Autism/Aspergers syndrome. Lewis et al. point out that many patients will describe auditory hallucinations that arise both inside and outside their heads, or will develop insight into the nature of their hallucinations only after decades of full belief in their external reality. In considering patients, these distinctions seem to have little significance in deciding diagnosis or considering appropriate treatment plans. One way the confusion between Autism/ Aspergers syndrome and schizophrenia can occur is when the psychiatrist ask the patients if they hear voices and they reply yes but mean the audible voices in the next room .

Schizophrenia And Autism: Shared Pathogenesis Via Prenatal Inflammation
In view of the emerging role of prenatal infection and associated inflammatory processes in the etiology of both schizophrenia and autism, we speculate that the pathogenesis of both disorders might have prenatal inflammation as a common pathway. In fact, this proposition might help explain why the two disorders share several phenotypic characteristics as discussed above. Numerous findings from pertinent rodent models suggest that this is indeed the case. Prenatal immune challenge in mice and rats leads to deficiency in social interaction and sensorimotor gating, the latter being assessed using the paradigm of prepulse inhibition of the acoustic startle reflex . Furthermore, offspring born to animals who sustained an immune challenge during gestation display deficits in working memory and abnormal executive functions such as impaired discrimination reversal learning and deficits in spatial and nonspatial information processing . These prenatal inflammation-induced behavioral manifestations are accompanied by neuroanatomical and neurochemical abnormalities seen in both schizophrenia and autism, including neuromorphological alterations in cerebellum, basal ganglia, and amygdala deficient Reelin expression in hippocampus and prefrontal cortex and alterations in serotonin synthesis and metabolism .

Family And Caregiver Schizophrenia Discussion Forum
Hello everyone, I am new heremy 24 year old son, who has dealt with HFA and OCD just graduated in May Magna Cum Laude with a Major in Psychology and a Minor in Philosophy, was accepted into three graduate schools online, and had two jobs lined up for the summer. 5 days after graduation, he spiraled into an acute psychotic break which seems to be more and more like Schizophrenia. I feel like I am losing him slowlylike his hold on reality is hanging by a threadjust hoping to find and offer support to others so we dont feel so alone
I am not a doctor though and that idea came to me just as a fellow mom thinking out loud. I do think your son probably should be evaluated professionally and that the professional you choose knows about how much your son takes on in any given, day, week or month. He or she may agree or disagree with my thoughts. I can say with either of my sons stress is the ultimate enemy of their mental wellness and stability. I think in many ways its the enemy for all of us. Just something to consider. Just because our kids can do certain things and do them well, doesnt mean that they necessarily should . Self awareness is key. Please know you are definitely not alone. I wish you and your son the very best going forward.

Microglia In Asd And Schizophrenia In Vivo Studies
Studying the activation of microglia in live subjects is of great value, particularly to monitor the evolution of neuroinflammation in the brain with age and the effect of medication. This information, combined with the indirect assessment of glial activation via peripheral blood biomarkers, could provide a clear picture of the processes that are occurring in vivo.
With the advent of non-invasive methods of studying brain function, such as functional magnetic resonance imaging and PET, valuable information can be extracted. For instance, PET can be used to investigate activation of microglia in diseased brain . The specific application of this technique to identify activated microglia is based on the ability of some markers, e.g., isoquinoline PK11195 -PK11195), to selectively bind to microglia that are activated, but not to resting cells. Subtle glial responses occur in areas of the brain that are microanatomically unchanged, providing evidence for some plasticity of the injured brain .
In a study by Suzuki et al., the application of PET using -PK11195) revealed substantial activation of microglia in patients with ASD . However, the regional distribution was not different between these subjects and controls. No other studies dealing with in vivo imaging studies on the activity of microglia in individuals with autism could be found.

Schizophrenia Prevalence May Be Threefold Higher In People With Autism

Dual diagnosis:
Autism and schizophrenia co-occur significantly more often than would be expected by chance, according to a new analysis of nearly 2 million people1.
Researchers have long suspected that autism and schizophrenia are related. The two conditions have overlapping traits, including sensory-processing problems and social difficulties, and they share gene-expression patterns in brain tissue. But studies of the prevalence of each condition among people diagnosed with the other have yielded inconsistent results.
Collating data from 11 studies, the new analysis found that schizophrenia is 3.6 times as common in individuals with autism as in controls. Autism likewise occurs more often in people with schizophrenia than in the general population, although the data, taken from six studies, are too variable for a single number to emerge.
Regardless of the way we look at it schizophrenia in autism or autism in schizophrenia the overlap between the two disorders is higher than wed expect, says Jennifer Foss-Feig, assistant professor of psychiatry at the Icahn School of Medicine at Mount Sinai in New York, who was not involved in the work.
The study does not offer clues to the origin of this overlap. Schizophrenia and autism as well as some environmental risk factors, such as in-utero exposure to inflammation.
Autism Or Schizophrenia: A Common Misdiagnosis
If a child is socially withdrawn and does not make eye contact when communicating with others, is the diagnosis schizophrenia or autism ? The two overlap because in most cases of schizophrenia, patients are often diagnosed during late adolescence to early thirties . Therefore, a diagnosis earlier in age is rare and often becomes misdiagnosed. According to the DSM-5, schizophrenic symptoms are categorized as either positive or negative and include delusions, hallucinations, disorganized speech, and catatonia, which is an irregularity in motor movement . Although this disorder is commonly diagnosed in young adults during late adolescence, there have been rare cases of schizophrenia in youth, which are those under the age of eighteen. While the likelihood of typical schizophrenia is 1% of people globally, the likelihood of childhood schizophrenia is 1 in 40,000 .
When a child is being evaluated by a psychologist, most often their early onset schizophrenia can be misdiagnosed as autism spectrum disorder, due to their overlap in social dysfunction symptoms . In the first two editions of the DSM , autism spectrum disorder was a subcategory under schizophrenia . It was considered, schizophrenia, childhood type . It was not until the publication of the third DSM that autism became its own category called Infantile Autism, which eventually was given the more expressive term, Autism Disorder .

Intercorrelations Among Panss And Ados Symptom Domains
Table 3 shows intercorrelations between ADOS-Positive, ADOS-Negative, PANSS-Positive, and PANSS-Negative across the entire sample. Of particular interest, there was a strong, significant correlation between ADOS-Negative and PANSS-Negative, r = 0.58, p< .001, suggesting overlapping content between the two scales. In contrast, ADOS-Positive and PANSS-Positive had a low, nonsignificant correlation, r = 0.16, p = .077, suggesting the positive symptom domains from either scale are tapping relatively distinct constructs.

Diagnosis Of Bipolar Disorder And Schizophrenia
There are no blood tests for diagnosing bipolar disorder or schizophrenia. Instead, your doctor will do a physical and psychological exam. During the exam, theyll ask you about any family history of mental disorders and your symptoms.
Your doctor may want to do a complete blood test to help rule out other conditions. They may also request an MRI or CT scan. Finally, they make ask you to agree to a drug and alcohol screening.
You may need to return for several visits before your doctor can make a diagnosis. These visits will help your doctor fully understand your symptoms. They may ask you to keep a daily record of your mood and sleep patterns. This can help your doctor see if any patterns emerge, such as manic and depressive episodes.
Treatment for both bipolar disorder and schizophrenia involves therapy and medication.
For bipolar disorder, psychotherapy may include:
- learning about changes in mood and how to effectively manage them
- educating family members about the disorder so they can be supportive and help with overcoming episodes
- helping you improve your relationships with friends and coworkers
- learning to manage your days to avoid possible triggers, such as a lack of sleep or stress
Your doctor may prescribe medications to control changes in mood and related symptoms, such as:
- mood stabilizers such as lithium

Aggression Schizophrenia And Autism/ Aspergers Syndrome
Patients with schizophrenia and Autism/ Aspergers Syndrome are more likely to be victims of aggression than perpetrators. . Lewis et al. points out that it also remains true that the evidence available indicates a small percentage of people with schizophrenia will commit a dispro- portionate amount of violence and even murder. The same is true of Autism/Aspergers Syndrome . Paranoid delusions can be a factor in the violence in both schizophrenia and Autism/ Aspergers Syndrome.
Andreasen points out that occasionally patients may perform violent acts such as injuring or tormenting animals, or attempting to injure or kill human beings. These features are observed in schizophrenia and Autism/Aspergers Syndrome . Persons with Autism/Aspergers Syndrome sometimes wave their arms and come to the attention of the police . Their behaviour and levels of distress in interpersonal situations can come across as appearing aggressive in both schizophrenia and Autism/Aspergers Syndrome.
Firstly What Is Autism
Neurodiversity advocates are encouraging better education and more acceptance and celebration of autism as prevalence of the condition rises. More parents are aware of early symptoms and red flags in young children which often leads to early diagnosis and intervention.
In the US The Diagnostic and Statistical Manual of Mental Disorders is used by medical professionals to diagnose autism spectrum disorders . The DSM-5 criteria for an autism diagnosis is divided into two core areas:
- Deficits in social communication/interaction
- Restricted/repetitive behaviors and/or sensory interests
Symptoms causing deficits in these two areas should cause significant issues in important areas of the childs life and should be present from early on .
Sensory issues and social withdrawal are also often associated with schizophrenia. In fact, many autism red flags are listed as early warning signs of schizophrenia. Lack of eye contact for example may indicate autism, but it could also predict schizophrenia where poor eye contact is associated with a lack of social motivation and withdrawal.
Autism sometimes presents in a manner where behavior may be misdiagnosed as psychotic symptoms. For example, repetitive behaviors and meltdowns may be diagnosed as catatonia . Along the same vein, the difficulty an individual with autism experiences due to impairment in reading others intentions may be classified as paranoia

What Switches Between Latent Versus Persistent Inflammation Trajectories
The induction of latent versus persistent neuroinflammatory trajectories subsequent to acute prenatal inflammation is likely to be controlled and modified by multiple mechanisms. First and foremost is the organism’s capability to mount appropriate anti-inflammatory, immunomodulatory, and/or immunosuppressive responses to acute inflammation, which might be smaller in individuals with autism as in those with schizophrenia. Indeed, autism seems to be associated with cellular and molecular processes that facilitate the persistence of inflammation. For example, autistic patients have reduced serum levels of the immunosuppressive cytokine TGF-1 and increased serum levels of the high-mobility group box 1 protein . HMGB1 is a highly conserved, ubiquitous protein that activates inflammation-associated immune responses . The persistence of neuroinflammation in autism may also be related to alterations in glutamate-immune interactions . Glutamate is a potent activator of microglia cells , and the presence of increased CNS glutamate levels together with up-regulation of specific glutamate receptor subtypes on microglia cells may facilitate the persistence of neuroinflammation subsequent to the induction of acute fetal inflammation .
Diagnostic And Behavioral Assessments
ASD Symptoms
ASD symptoms were measured using the ADOS-2 . The ADOS-2 is a gold-standard assessment tool used to assist clinician judgment in making decisions about a possible ASD diagnosis. It is commonly used in ASD research to confirm diagnoses in a standardized manner and to estimate the severity of ASD traits . The ADOS-2 was administered by trained, research-reliable clinicians and consists of semistructured activities and conversations meant to sample a participants real-world social behavior and core autistic characteristics related to language and communication, reciprocal social interaction, imagination and creativity, stereotyped behaviors and restricted interests, and other atypical behaviors. The ADOS-2 algorithm sums across a subset of scored items in order to categorize participants into autism , autism-spectrum , and non-spectrum.

Is There A Link Between Autism And Schizophrenia
A review and meta analysis examined the presence of autistic symptoms in schizophrenia spectrum disorders. The two conditions share common cognitive features like weak central coherence and impairment in theory of mind and conclusions from the study show that individuals with schizophrenia have higher levels of autistic symptoms in comparison to control groups.
Not only do those with schizophrenia have higher levels of autistic symptoms, study results showed the incidence of psychiatric comorbidities like schizophrenia among individuals with autism were significantly higher than in a comparison group. The study also suggests the incidence of mental disorders were influenced by autism subtypes and gender. The authors found that females with aspergers had a significantly higher risk for schizophrenia spectrum disorder than males. The study further concluded that individuals with pervasive developmental disorders had a higher risk for major depressive disorder rather than ASD.
Regarding Education And Occupation Of The Parents
In this study, there was no significant statistical difference regarding the relationship between the severity of autistic traits in the children and the education and the occupation of their parents in the case and control group.
In agreement with our study, Salah El-Deen and Mahdy reported that there was no statistical difference relation between the severity of autistic traits in the children and the education and the occupation of schizophrenic parents. Other studies that carried on ASD children of non-psychiatric parents revealed that the risk of ASD was not associated with education or occupation of the parents or maternal education .
On the other hand, Rai et al. mentioned in their study that children of parents with manual occupations were at higher risk of ASD. This is inconsistent with the results of our study maybe because of the cultural differences and this study was applied in Sweden, a country that has routine screening for developmental problems, free universal healthcare, and thorough protocols for diagnoses of autism.

Early Signs Of Schizophrenia
Living with her autism spectrum disorder for so many years, we had all come to terms with it by the time Wendy was in high school. She was never going to have many friends, but the kids in school were nice to her and she loved learning, especially science. She planned to go to college to become a chemist.
Then we started to notice some troubling behaviors and moods in Wendy. At the time, we had no idea these were typical early signs of psychosis. First her grades started to drop, which was unusual because she had never gotten less than a B in school. She complained that it was hard to concentrate. She also stopped taking care of her appearance I actually had to remind her to take a shower every day.
Early psychosis begins gradually, as we learned later. So it wasnt obvious at all that this was the explanation, especially with Wendys autism. She has never been demonstrative or emotional, but during this time she seemed even more distant.
Her father and I didnt get too worried until she started talking about seeing insects crawling on her skin and hearing a voice just to her left. One thing that has been beneficial in terms of Wendys autism is that she has never tried to hide anything or be dishonest. She told us right away what she was experiencing. We knew that something really was wrong.
