The 1442 eyes studied (mean age: 52.48Â±11 years) included 816 eyes with a cataract and 626 eyes with a clear lens. Irrespective of age and AL, the distribution of mean lens thickness per clear lens and different cataract types is depicted in Table 1a.
While cerebral aneurysms are often symptomless, they can cause headaches on occasion. While not common, even an aneurysm that has not ruptured may cause headaches in some individuals. A person may notice an abrupt, severe headache, or a series of headaches different from their âusualâ ones.
This may account for the myths that unruptured aneurysms or arteriovenous malformations cause headache and that migraine can eventually lead to stroke. Sometimes, however, headaches do warn of cerebrovascular disease or occur as part of that disease. The presence of headache may aid in or hinder diagnosis.eadache is a common affliction of humanity. The physician evaluating a patient who happens to have a history of headaches may naturally consider them as part of the disease when formulating a diagnosis, thus attributing undue significance to ordinary functional headaches.
