Researchers in Japan have identified lower levels of a critical lipid in the brains of people with schizophrenia, which could lead to new treatments for the brain disorder. Ironically, Bleuler had intended to clarify matters by replacing the older, even more misleading term of dementia præcox [‘dementia of early life’]. In the first approach (regional), the researchers retrospectively analyzed the data from 3,045 Parkinson’s disease patients treated from 2004 to 2019 in southwestern Finland, and 3,045 age- and sex-matched people without the disease (control group).

Another study in 2009 by Simon Fraser University researchers identifies a link between autism and schizophrenia: "The SFU group found that variations in four sets of genes are related to both autism and schizophrenia… Schizophrenia. This higher risk may be associated with medication-induced changes in the brain’s dopamine system — also affected in Parkinson’s patients — or disease-associated mechanisms, and further studies are needed to clarify this, the researchers noted. The frequency of SCD and schizophrenia cases in the control group also was assessed.

The regional data also showed that people with SCD or schizophrenia were four times more likely to develop Parkinson’s than those without the psychiatric condition, while the national analysis found a 1.17-times higher risk of Parkinson’s among SCD patients only. Importantly, these findings challenge the prevailing idea that the co-occurrence of Parkinson’s disease and schizophrenia is “rare because these diseases are associated with opposite alterations in the brain’s dopamine system,” Tomi Kuusimäki, the study’s first author and a PhD student at the University of Turku, in Finland, said in a press release. The study, “Increased Risk of Parkinson’s Disease in Patients With Schizophrenia Spectrum Disorders,” was published in the journal Movement Disorders. 2020 Sep 2;10(9):601. doi: 10.3390/brainsci10090601.

[Genetic and pharmacological effects on prefrontal cortical function in schizophrenia]. A professor … A review of 65 studies of individuals with schizophrenia who had never been treated with antipsychotic medications indicates significant abnormalities in brain structure and function. The team also emphasized that this increased risk was clearly observed despite the fact that the analyses did not include patients with the most severe SCD, because they usually die before the typical age of Parkinson’s onset.

Molina V, Reig S, Pascau J, Sanz J, Sarramea F, Gispert JD, Luque R, Benito C, Palomo T, Desco M. Psychiatry Res. The absence of an increased risk for people with schizophrenia in the national approach may be due to the diagnostic classification, as a SCD diagnosis often may precede a schizophrenia diagnosis, the team noted. It does not provide medical advice, diagnosis or treatment. People with schizophrenia spectrum disorder have an increased risk of developing Parkinson’s disease later in life, according to both regional and nationwide data from Finland. Results from both approaches showed that a greater proportion of Parkinson’s patients had been diagnosed previously with SCD than matched controls (0.76% vs. 0.16% in the regional study and 1.5% vs. 1.31% in the national analysis).

Marta Figueiredo holds a BSc in Biology and a MSc in Evolutionary and Developmental Biology from the University of Lisbon, Portugal. People with schizophrenia have a lower quality of life than the general population. As such, the main treatments for these conditions typically have opposing mechanisms of action; those mimicking dopamine are used to alleviate Parkinson’s symptoms, whereas those suppressing it are used commonly in schizophrenia patients. She is currently finishing her PhD in Biomedical Sciences at the University of Lisbon, where she focused her research on the role of several signalling pathways in thymus and parathyroid glands embryonic development. She graduated with a BSc in Genetics from the University of Newcastle and received a Masters in Biomolecular Archaeology from the University of Manchester, England. Parkinson’s is characterized by a progressive loss of dopamine-producing cells in a brain region that controls movement, while people with schizophrenia typically have an overactive dopamine system, especially in reward-related brain regions.

Schizophrenia is a serious brain disorder that distorts the way a person thinks, acts, expresses emotions, perceives reality, and relates to others. Based on their differences, these conditions are considered to occur rarely in the same person. It is possible that most severe cases of SCD lead “to a particularly increased PD risk over time, a risk that is neutralized by the increased mortality,” the researchers wrote.

People with schizophrenia -- the most chronic and disabling of the major mental illnesses -- often have problems functioning in society, at work, at school, and in relationships. Neurological and neuropsychological measures show the most consistent and largest group differences between those affected and normal controls. It is concluded that schizophrenia is a brain disease in the same sense that Parkinson's disease and multiple sclerosis are, and that the brain abnormalities in schizophrenia are inherent in the disease process and not medication-related. The challenge for the future is to use the new molecular techniques to study these brain areas and elevate our understanding of schizophrenia's etiology to the next level.
