It's important to consult with a qualified healthcare professional for personalized medical advice.
The vertebral arteries are major blood vessels that supply blood to the brainstem, including the reticular formation, which is involved in regulating arousal and consciousness. If there is a tortuous (twisted or curved) thickened vertebral artery, it could potentially lead to reduced blood flow to the brainstem and affect the reticular formation's function.
However, psychosis is a complex and multifactorial condition with various potential causes, including genetic, environmental, and psychological factors. While reduced blood flow to the brainstem might theoretically affect the reticular formation and, in turn, influence arousal and consciousness, there isn't a direct and straightforward link between a tortuous vertebral artery and psychosis.
Psychosis is more commonly associated with conditions like schizophrenia, bipolar disorder, severe depression, or drug-induced states rather than vascular issues alone. If someone is experiencing symptoms of psychosis or any other neurological or psychiatric symptoms, it's essential to seek medical attention promptly to undergo a thorough evaluation by a qualified healthcare professional. They can properly assess the individual's condition and determine the underlying cause, if any, and recommend appropriate treatment options.
