Abstract: Although some studies have reported perceptual changes in psychosis, no definitive conclusions have been drawn about visual disturbances that are related to bipolar disorder (BPD). The purpose of the present study was to evaluate colour vision in BPD patients. Data were recorded from 24 participants: healthy control group (n = 12) and type 1 BPD group (n = 12). The participants were 20–45 years old and they were free from neurological disorders and identifiable ocular disease and had normal or corrected-to-nor… Show more

“…With respect to color discrimination, findings based on a sample of 20 male patients, aged 18 between 45 years old with schizophrenia and manic-depressive psychosis, indicated that when their right hemisphere was depressed, the identification of color by saturation, shade, and color tone was impaired [61]. More recently, the association of color vision with bipolar disorder explored [62]. The general findings suggest that people suffering from depression are likely to reveal their mood through their choice of colors (such as preference for darker shades) in everyday life situations [63].…”

“…For example, the use of different medications has been a confounding factor in several previous studies. 4,20,21 The exact mechanism of the medications' Visual impairment in schizophrenia adverse effects and its relationship with illness duration are not fully understood. As mentioned above, some studies on this issue have used different methods and paradigms but have yielded similar results.…”

“…A landmark study [11] laid the foundation for a deep understanding of the subject. Colour perception choices are quite strong and they are dependent on a number of underlying factors such as personality types [12,6,7,8,13,14], ethnic background of the subjects [15][16][17][18], age [19][20][21][22][23][24], gender [25][26][27][28][29], education [30], mental status and information processing in such conditions [31][32][33]. It has been seen that brain activity is modulated by colour preference which implies a correlation between colour preference and personality traits; and colour preference could be a pervasive aspect of visual processing [34].…”

“…The protein opsin is a fundamental component of photopigment that plays the vital role of tuning colour photoreceptors to specific wavelengths of light ie; colour and provides a richer colour experience [47,43]. The complex neurophysiological mechanism underlying colour recognition is regulated by genes [40,46] and gets altered by impairments [48] and disorders [31,32]. A functional neuropsychological system forms the basis of any personality trait and this is moulded by the combined effect of genes and environment [49].…”
