Excessive levels of acetylcholine can lead to what type of psychological state?

Excessive levels of acetylcholine in the brain are linked to a variety of neurological and psychological effects due to its role as a neurotransmitter involved in many functions, including mood regulation and cognitive processes. High acetylcholine levels can cause overstimulation of the nervous system, leading to conditions often associated with delusions.

Delusions are false beliefs that are strongly held despite evidence to the contrary and can arise from disturbances in normal neurotransmitter functioning. This neurotransmitter's influence in enhancing the processing of information and possible hyperactivity can contribute to a distorted perception of reality.

While fatigue, anxiety, and insomnia are also symptoms that can occur due to various neurotransmitter imbalances, they are not primarily associated with high acetylcholine levels to the same extent as delusions. Understanding the relationship between acetylcholine and these psychological states is essential for comprehending the broader context of neurotransmitter function in mental health.
