What could cause dizziness and blurred vision, and what should I do about it?

　　Mental fogginess and blurred vision may be caused by physiological factors, or by pathological conditions such as glaucoma or cervical spondylosis. Patients can receive treatment through general management or medication. Specific details are as follows:

　　I. Physiological Factors

　　Long-term sleep deprivation, excessive mental stress, and anxiety may affect the brain and lead to symptoms such as dizziness and blurred vision. It is important to get adequate rest and avoid overexertion.

　　II. Pathological Factors

　　1. Glaucoma

　　Elevated intraocular pressure or insufficient blood supply to the optic nerve may result in visual field defects, causing symptoms such as dizziness, confusion, and blurred vision, often accompanied by headache and nausea. Under a doctor's guidance, patients may use medications such as carteolol hydrochloride ophthalmic solution or brimonidine tartrate ophthalmic solution.

　　2. Cervical Spondylosis

　　Degenerative changes in the cervical spine can lead to segmental instability, compressing or irritating the vertebral artery and resulting in vertebrobasilar insufficiency. This may cause headaches and mental fogginess. Under medical supervision, patients may take medications such as diclofenac sodium sustained-release tablets or Jinfukang granules.

　　In addition to the above causes, these symptoms may also result from cerebral hypoperfusion or cerebral hemorrhage. It is recommended that patients seek timely evaluation at a reputable medical facility upon experiencing such symptoms. Maintaining a positive mindset and avoiding emotional agitation are also important.
