Genetic Predisposition: The increased likelihood of developing a specific condition (in this case, a mental illness) due to inherited genes.
Neurotransmitters: Chemical messengers that transmit signals between nerve cells in the brain. Imbalances or abnormalities in these neurotransmitters have been linked to various mental disorders.
Brain Abnormalities: Structural or functional irregularities within the brain, such as differences in size or activity levels, which can contribute to the development of mental illnesses.
