Can a pituitary adenoma cause chronic insomnia?

Yes, a pituitary adenoma can cause chronic insomnia, particularly if it affects hormone levels or causes pressure on surrounding brain structures. Increased levels of certain hormones, such as cortisol from an adenoma causing Cushing's disease, can disrupt sleep patterns. Additionally, the physical presence of the tumor may lead to headaches or other symptoms that interfere with sleep quality. It is essential for individuals experiencing chronic insomnia to consult a healthcare professional for proper evaluation and treatment.
