Disorganized thinking: Difficulty in organizing thoughts, leading to confused speech and behaviour.
Lack of motivation: Reduced interest and engagement in daily activities, including work, school and social interactions
Etiology of Psychosis
Genetic Factors: Genetic predisposition, including inherited risk factors can contribute to development of psychosis.
Neurodevelopmental factors: Disruptions in brain development, such as during fetal development or early childhood can increase risk of psychosis.
Environmental factors: Exposure to stressful life events, trauma, substance abuse or infections can trigger the onset of psychosis.
Neurochemical imbalances: Dysregulation of neurotransmitters, such as dopamine and glutamate can lead to emergence of psychotic symptoms
