Learn more here."],"attrs_boilerpipe_text":"People with schizophrenia may not show any signs leading up to the condition’s onset. When they do occur, they can vary widely. They may include changes in personal hygiene habits or a loss of interest in activities.\nSchizophrenia is a mental health condition associated with delusions, hallucinations, “negative” symptoms, and cognitive decline. The condition can majorly affect a person’s overall well-being and their work, schooling, and home life.\nMany people with schizophrenia go through an early stage where symptoms develop and worsen. This can look different for everyone.\nThis article reviews what the medical community knows about the early stages of schizophrenia, signs at different ages, symptoms, and more.\nA 2017 study notes that about\n75%\nof people with\nschizophrenia\npass through a prodromal stage. This is a period when subtle changes to thoughts, behaviors, and moods start to occur.\nThe progression from displaying early signs to having the criteria for a diagnosis of schizophrenia can take months to years. However, estimates in the same study suggest that only about 1 in 4 people with subthreshold\npsychosis symptoms\n, nonspecific\nanxiety\n, and affective symptoms develop schizophrenia.\nThe prodromal stage does not involve a set of specific symptoms. Instead, symptoms can gradually develop over this period.\nMedical professionals refer to schizophrenia in children under the age of 18 as early-onset schizophrenia. It develops in about\n0.4% of children\naged 5–18 years old and is even more rare in those under 5.\nAssessment and diagnostic criteria for children are the same as for adults. However, doctors often misdiagnose it as another condition, such as\nobsessive–compulsive disorder (OCD)\n, an affective condition, or another psychotic disorder.\nBefore diagnosis, a child may show signs such as:\nsocial withdrawal and\nisolation\nacademic difficulties\nbehavioral issues\nspeech and language difficulties\ncognitive issues\nSchizophrenia in teenagers is also known as early-onset schizophrenia unless they are 18 or over. Often, symptoms and signs\ndevelop slowly\nover time. Family members or friends may notice differences in the teen’s thinking patterns, moods, and social functioning.\nSome early signs in teens can include common and nonspecific adolescent behaviors,\nsuch as\n:\nirritability\nchanging friend groups\na drop in grades\nsleep problems\nisolation\nan increase in unusual thoughts or\nsuspicions\nLate-onset schizophrenia occurs in adults after the age of 45. About\n20%\nof all cases develop at age 40–60.\nVery late-onset schizophrenia occurs when symptoms present after the age of 60. About\n60%\nof psychosis in older people is secondary to neurodegenerative disorders, which means distinguishing between schizophrenia and secondary disorders plays a part in diagnosis.\nSome evidence\nsuggests\nit is more common in females, those with high levels of occupational functioning, and people in marital relationships. Symptoms often include severe paranoid delusions and more visual, tactile, and\nolfactory hallucinations\n.\nSymptoms or signs of schizophrenia\ncan begin\nweeks, months, or years before clinical diagnosis. Diagnosis can occur at any age. The condition affects people of all genders equally.\nEarly onset\nEarly onset schizophrenia occurs when a person\nreceives a diagnosis\nin childhood or in their teens. Diagnosis in children is less common than in teens or young adults.\nLate-onset\nLate-onset schizophrenia first appears when a person is\n40 years old\nor older. Very late-onset occurs when a person receives a diagnosis after the age of 60.\nTreatment for schizophrenia can be effective and help a person maintain or regain their typical life activities.\nIt often involves a multidisciplinary approach that\nmay include\n:\nantipsychotic medications\npsychotherapy\ncognitive behavioral therapy (CBT)\nemployment support\nhospitalization\nAdditional therapies and support can help a person maintain more or all of their independence. Treatments can include group therapy, coordinated care, and treating any alcohol or drug\ndependencies\na person may have developed.\nThe following are answers to some questions people commonly ask about schizophrenia.\nWhat are three warning signs of schizophrenia?\nSchizophrenia often starts slowly. Leading up to diagnosis or the first clinical symptoms, a person\nmay display\nchanges to their:\nthoughts\nsocial behaviors\nmood\nThese are generally nonspecific and may initially go unnoticed.\nHow does schizophrenia start?\nSchizophrenia can start gradually or with sudden symptoms. If symptoms come on slowly, friends and family may initially notice subtle changes in behaviors, mood, and thought patterns.\nSchizophrenia is a mental health condition that causes changes in thinking, feeling, and behavior. Although it can develop at any age, symptoms typically appear between the late teens and early adulthood.\nEarly signs can occur gradually, and people may not notice them at first or mistake them for other issues. They can also mirror typical behaviors that vary with age, such as developmental delays in children or conditions secondary to\ndementia\nin older adults.\nTreatment can help a person with schizophrenia maintain some or all of their independence and live a fulfilling life.","attrs_markdown":"- Health Conditions\n  ### Health Conditions\n  -

Boilerpipe Text	People with schizophrenia may not show any signs leading up to the condition’s onset. When they do occur, they can vary widely. They may include changes in personal hygiene habits or a loss of interest in activities. Schizophrenia is a mental health condition associated with delusions, hallucinations, “negative” symptoms, and cognitive decline. The condition can majorly affect a person’s overall well-being and their work, schooling, and home life. Many people with schizophrenia go through an early stage where symptoms develop and worsen. This can look different for everyone. This article reviews what the medical community knows about the early stages of schizophrenia, signs at different ages, symptoms, and more. A 2017 study notes that about 75% of people with schizophrenia pass through a prodromal stage. This is a period when subtle changes to thoughts, behaviors, and moods start to occur. The progression from displaying early signs to having the criteria for a diagnosis of schizophrenia can take months to years. However, estimates in the same study suggest that only about 1 in 4 people with subthreshold psychosis symptoms , nonspecific anxiety , and affective symptoms develop schizophrenia. The prodromal stage does not involve a set of specific symptoms. Instead, symptoms can gradually develop over this period. Medical professionals refer to schizophrenia in children under the age of 18 as early-onset schizophrenia. It develops in about 0.4% of children aged 5–18 years old and is even more rare in those under 5. Assessment and diagnostic criteria for children are the same as for adults. However, doctors often misdiagnose it as another condition, such as obsessive–compulsive disorder (OCD) , an affective condition, or another psychotic disorder. Before diagnosis, a child may show signs such as: social withdrawal and isolation academic difficulties behavioral issues speech and language difficulties cognitive issues Schizophrenia in teenagers is also known as early-onset schizophrenia unless they are 18 or over. Often, symptoms and signs develop slowly over time. Family members or friends may notice differences in the teen’s thinking patterns, moods, and social functioning. Some early signs in teens can include common and nonspecific adolescent behaviors, such as : irritability changing friend groups a drop in grades sleep problems isolation an increase in unusual thoughts or suspicions Late-onset schizophrenia occurs in adults after the age of 45. About 20% of all cases develop at age 40–60. Very late-onset schizophrenia occurs when symptoms present after the age of 60. About 60% of psychosis in older people is secondary to neurodegenerative disorders, which means distinguishing between schizophrenia and secondary disorders plays a part in diagnosis. Some evidence suggests it is more common in females, those with high levels of occupational functioning, and people in marital relationships. Symptoms often include severe paranoid delusions and more visual, tactile, and olfactory hallucinations . Symptoms or signs of schizophrenia can begin weeks, months, or years before clinical diagnosis. Diagnosis can occur at any age. The condition affects people of all genders equally. Early onset Early onset schizophrenia occurs when a person receives a diagnosis in childhood or in their teens. Diagnosis in children is less common than in teens or young adults. Late-onset Late-onset schizophrenia first appears when a person is 40 years old or older. Very late-onset occurs when a person receives a diagnosis after the age of 60. Treatment for schizophrenia can be effective and help a person maintain or regain their typical life activities. It often involves a multidisciplinary approach that may include : antipsychotic medications psychotherapy cognitive behavioral therapy (CBT) employment support hospitalization Additional therapies and support can help a person maintain more or all of their independence. Treatments can include group therapy, coordinated care, and treating any alcohol or drug dependencies a person may have developed.

When they do occur, they can vary widely. They may include changes in personal hygiene habits or a loss of interest in activities. Schizophrenia is a mental health condition associated with delusions, hallucinations, “negative” symptoms, and cognitive decline. The condition can majorly affect a person’s overall well-being and their work, schooling, and home life. Many people with schizophrenia go through an early stage where symptoms develop and worsen. This can look different for everyone. This article reviews what the medical community knows about the early stages of schizophrenia, signs at different ages, symptoms, and more. ### A note about sex and gender Sex and gender exist on spectrums. This article will use the terms “male,” “female,” or both to refer to sex assigned at birth.

This is a period when subtle changes to thoughts, behaviors, and moods start to occur. The progression from displaying early signs to having the criteria for a diagnosis of schizophrenia can take months to years. However, estimates in the same study suggest that only about 1 in 4 people with subthreshold [psychosis symptoms](https://www.medicalnewstoday.com/articles/248159), nonspecific [anxiety](https://www.medicalnewstoday.com/articles/323454), and affective symptoms develop schizophrenia. The prodromal stage does not involve a set of specific symptoms. Instead, symptoms can gradually develop over this period. ## [Early signs of schizophrenia in children]() Medical professionals refer to schizophrenia in children under the age of 18 as early-onset schizophrenia. It develops in about [0\.4% of children](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6345123/) aged 5–18 years old and is even more rare in those under 5. Assessment and diagnostic criteria for children are the same as for adults. However, doctors often misdiagnose it as another condition, such as [obsessive–compulsive disorder (OCD)](https://www.medicalnewstoday.com/articles/178508), an affective condition, or another psychotic disorder. Before diagnosis, a child may show signs such as: - social withdrawal and [isolation](https://www.medicalnewstoday.com/articles/isolation-and-mental-health) - academic difficulties - behavioral issues - speech and language difficulties - cognitive issues ## [Early signs of schizophrenia in teenagers]() Schizophrenia in teenagers is also known as early-onset schizophrenia unless they are 18 or over. Often, symptoms and signs [develop slowly](https://www.nimh.nih.gov/health/topics/schizophrenia) over time. Family members or friends may notice differences in the teen’s thinking patterns, moods, and social functioning. Some early signs in teens can include common and nonspecific adolescent behaviors, [such as](https://www.nami.org/About-Mental-Illness/Mental-Health-Conditions/Schizophrenia): - [irritability](https://www.medicalnewstoday.com/articles/325564) - changing friend groups - a drop in grades - [sleep problems](https://www.medicalnewstoday.com/articles/327339) - isolation - an increase in unusual thoughts or [suspicions](https://www.medicalnewstoday.com/articles/what-is-paranoia) ## [Early signs in young adults]() Schizophrenia [typically starts](https://www.nimh.nih.gov/health/statistics/schizophrenia) at different ages based on gender. Males tend to develop the condition between their late teens and early 20s. Females tend to develop schizophrenia in their 30s. Early signs and symptoms can come on gradually and may be very subtle at first. Some potential signs include: - social isolation or withdrawal - reduced levels of [personal hygiene](http://v/) - engaging in [socially inappropriate behaviors](https://www.medicalnewstoday.com/articles/325402) - [jumbled speech](https://www.medicalnewstoday.com/articles/324764) - [flat affect](https://www.medicalnewstoday.com/articles/319357) ## [Early signs in adults over the age of 45]() Late-onset schizophrenia occurs in adults after the age of 45. About [20%](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4418466/) of all cases develop at age 40–60. Very late-onset schizophrenia occurs when symptoms present after the age of 60. About [60%](https://karger.com/nps/article/81/2/98/828828/Neuroinflammation-in-Late-Onset-Schizophrenia) of psychosis in older people is secondary to neurodegenerative disorders, which means distinguishing between schizophrenia and secondary disorders plays a part in diagnosis. Some evidence [suggests](https://library.neura.edu.au/schizophrenia/illness-course-and-outcomes/late-onset-schizophrenia/) it is more common in females, those with high levels of occupational functioning, and people in marital relationships. Symptoms often include severe paranoid delusions and more visual, tactile, and [olfactory hallucinations](https://www.medicalnewstoday.com/articles/322698). Less frequently, a person may experience [disorganization](https://www.medicalnewstoday.com/articles/192361) and [negative symptoms](https://www.medicalnewstoday.com/articles/negative-symptoms-of-schizophrenia). ### Learn more about schizophrenia - [What to know about the stages of schizophrenia](https://www.medicalnewstoday.com/articles/stages-of-schizophrenia) - [What are the different types of schizophrenia?](https://www.medicalnewstoday.com/articles/192770) - [Is there a cure for schizophrenia?](https://www.medicalnewstoday.com/articles/is-there-a-cure-for-schizophrenia) - [What to know about the positive symptoms of schizophrenia](https://www.medicalnewstoday.com/articles/positive-symptoms-of-schizophrenia) ## [When do symptoms begin?]() Symptoms or signs of schizophrenia [can begin](https://www.nimh.nih.gov/health/statistics/schizophrenia) weeks, months, or years before clinical diagnosis. Diagnosis can occur at any age. The condition affects people of all genders equally. ### Early onset Early onset schizophrenia occurs when a person [receives a diagnosis](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6345123/) in childhood or in their teens. Diagnosis in children is less common than in teens or young adults. ### Late-onset Late-onset schizophrenia first appears when a person is [40 years old](https://karger.com/nps/article/81/2/98/828828/Neuroinflammation-in-Late-Onset-Schizophrenia) or older. Very late-onset occurs when a person receives a diagnosis after the age of 60. ## [Schizophrenia treatment]() Treatment for schizophrenia can be effective and help a person maintain or regain their typical life activities. It often involves a multidisciplinary approach that [may include](https://www.nimh.nih.gov/health/topics/schizophrenia): - [antipsychotic medications](https://www.medicalnewstoday.com/articles/schizophrenia-second-generation-antipsychotics) - [psychotherapy](https://www.medicalnewstoday.com/articles/156433) - [cognitive behavioral therapy (CBT)](https://www.medicalnewstoday.com/articles/296579) - employment support - hospitalization Additional therapies and support can help a person maintain more or all of their independence. Treatments can include group therapy, coordinated care, and treating any alcohol or drug [dependencies](https://www.medicalnewstoday.com/articles/323465) a person may have developed. ## [Frequently asked questions]() The following are answers to some questions people commonly ask about schizophrenia. ### What are three warning signs of schizophrenia? Schizophrenia often starts slowly. Leading up to diagnosis or the first clinical symptoms, a person [may display](https://www.nimh.nih.gov/health/topics/schizophrenia) changes to their: - thoughts - social behaviors - mood These are generally nonspecific and may initially go unnoticed. ### How does schizophrenia start? Schizophrenia can start gradually or with sudden symptoms. If symptoms come on slowly, friends and family may initially notice subtle changes in behaviors, mood, and thought patterns. For more research-backed information and resources on mental health and well-being, please visit [our dedicated hub](https://www.medicalnewstoday.com/mental-health). ## [Summary]() Schizophrenia is a mental health condition that causes changes in thinking, feeling, and behavior. Although it can develop at any age, symptoms typically appear between the late teens and early adulthood. Early signs can occur gradually, and people may not notice them at first or mistake them for other issues. They can also mirror typical behaviors that vary with age, such as developmental delays in children or conditions secondary to [dementia](https://www.medicalnewstoday.com/articles/142214) in older adults. Treatment can help a person with schizophrenia maintain some or all of their independence and live a fulfilling life. - [Mental Health](https://www.medicalnewstoday.com/categories/mental-health) - [Schizophrenia](https://www.medicalnewstoday.com/categories/schizophrenia) - [Psychology / Psychiatry](https://www.medicalnewstoday.com/categories/psychology-psychiatry) ### How we reviewed this article: Sources Medical News Today has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical journals and associations.
