It is generally believed that headaches are most often caused because of a high blood pressure. This it not always true, there are many more reasons why someone has a headache and high blood pressure is only one of the possible causes. Most often headaches are not the primary symptom. Off course there are some disorders like cluster headaches or chronic headaches, but most of the time they are caused by other related symptoms.
When you think of headaches your probably think of Migraine. These two are highly related to each other although many migraine attacks go without any headaches at all. Although there are many possible causes and symptoms that coincide with a headache, this article will point out information about headaches and blurred vision.
Some individuals experience headaches with blurred vision. This could be with a sudden onset or coincide with migraine attacks. It is not easy to tell if the blurred vision is a cause of the headaches or maybe the other way around. When you experience blurred vision this is most often not something to take too lightly. Sometimes a blurred vision is caused by a migraine attack but then it should go away as soon as the migraine has passed. Another explanation might be when you did an exert performance that cost you a lot of energy. Sometimes this can cause a blurred vision because your body is very tired.
However, most of the times a blurred vision is something more, especially when the vision is blurred all the time and not only with headaches. When that is the case then there are some neurological disorders that might cause the blurred vision, consulting a doctor might be a good idea.
The first thing a doctor want to find out is if it is a neurological problem or an eye problem. When you close one eye and still have the blurred vision than it is unlikely that it is a local eye problem because it effects both eyes. If the blurring stops when you close one eye than it is possibly a local eye problem. Your doctor will ask for a VEP (Visually Evoked Potential) to state this fact. A possible cause for blurring in one eye might be optical neuritis.
Another possible cause could be pseudotumor cerebri (elevated intracranial pressure). The pressure in the brain will rise although there is no tumor to be found. The symptoms of this are blurred vision, buzzing ears, headaches, nausea and vomiting. If nothing is done about this, vision loss is a serious threat. Your doctor will ask for a CT scan and a Spinal Tap. A spinal tap will control the pressure in the brain and this often releases the tension for a short time. Medication and sometimes surgery have to give relief to the intracranial pressure.
Although headaches and blurred vision do not always form a serious condition, you should not taken this symptoms lightly. Especially when the vision stays blurred all the time you should consult your doctor. The information provided here is intended for medical education.
