Thereafter incidence declines to a plateau at later ages. Statistics indicate that schizophrenia affects approximately 24 million Americans.

Schizophrenia incidence shows a steep increase culminating at age 15 to 25 years in males.
Schizophrenia age range. All patients age 60 years and older in contact with the Mental Health Organization in a psychiatric catchment area in Amsterdam the Netherlands diagnosed with schizophrenia schizoaffective disorder or delusional disorder. The old-old those 75 years and older and young-old aged 55 to 74 years. The age range of maximum risk for schizophrenia extends from 15 to 30 years old.
One facet of its diversity is the age at onset. As noted previously first contact with mental health services is frequently delayed from the onset of the illness and occurs between 25 and 35 years of age for both men and women. Aging is associated with exacerbation of schizophrenia symptoms.
1 Another peak particularly among women occurs in mid-life. Positive symptoms tend to lessen with age but negative symptoms and cognitive impairments continue to worsen. Schizophrenia is typically diagnosed in the late teens years to early thirties and tends to emerge earlier in males late adolescence early twenties than females early twenties early thirties.
The prevalence of schizophrenia in adults age 65 and older ranges from 0105. In females it reaches a first peak at age 15 to 30 years and a second flatter peak at menopausal age 44-49 years. Schizophrenia is a diverse disorder.
Background Over the last few decades research regarding the age of onset of schizophrenia and its relationship with other clinical variables has been incorporated into clinical practices. Let us assume that the schizophrenia age-of-onset distribution curve for the Gottesman cohort is identical to that of the USA modeled in Section 22. Who is affected by schizophrenia.
Schizophrenia is uncommon in children under the age of 12 and hard to identify in the early phases. Although extremely rare before the age of 10 the incidence of schizophrenia rises steadily through adolescence to reach its peak in early adult life. Men tend to get develop schizophrenia slightly earlier than women.
There are currently two generations of older adults with schizophrenia. Whereas most males become ill between 16 The average age of onset is 18 in men and 25 in women. The age range for the Gottesman cohort in Table 2 was reported to be with the median age being 37 y.
Onset is quite rare for people under 10 years of age or over 40 years. The incidence of schizophrenia peaks between 10 and 25 years for men and between 25 and 35 for women. About 23 of people with schizophrenia experience their first episode after the age of 40.
However reports of potential differences in demographic and clinical characteristics between early- and adult-onset schizophrenia spectrum disorders have been controversial. For men the onset tends to occur about 45 years earlier than for women. Schizophrenia is one of the most devastating psychiatric disorders to affect children and adolescents.
A sudden onset of the psychotic symptoms of schizophrenia frequently occurs in middle to late adolescence. Between the ages of 15 and 25. 2 Although more adults with schizophrenia are living longer their life expectancy is still shorter than that of unaffected individuals.
12 More subtle changes in cognition and social relationships may precede the actual diagnosis often by years.
