Reasons might be variable medical infrastructure in different countries such as availability of diagnostic methods. Subarachnoid hemorrhage thus could go undiagnosed and a patient may die without prior diagnosis. The common age for subarachnoid hemorrhage is between 40 and 60 years, and women are more affected. Additionally differences between races have been detected in terms of the occurrence of subarachnoid hemorrhage. So black people are statistically more affected. The risk factors for occur of subarachnoid hemorrhage can be separate in modifiable and non-modifiable factors. Examples for modifiable factors are smoking, arterial hypertension and excess alcohol consumption. Familial disposition or genetic diseases are non-modifiable factors.
