The investigators found that the risk of developing a progressive dementia before the age of 65 was 1.8% for people with schizophrenia compared to only 0.6% for those without schizophrenia. By the age of 80, people with schizophrenia remained at higher risk for dementia but the difference between the 2 populations was less striking: 7.4% for people with schizophrenia and 5.8% for people without schizophrenia. These data indicate that the people with schizophrenia had a greater risk not only for developing dementia but also for developing it at a younger age. In fact, 22.4% of the individuals with schizophrenia who went on to develop dementia (211 of 944) were diagnosed with dementia before 65. In comparison, only 6.3% of the people with dementia who did not have schizophrenia were diagnosed with dementia at this relatively early age.
