Brain aneurysms can occur without warning and, if left untreated, can lead to a stroke or even death. It is vital to know the primary symptoms and what to look for in order to identify the onset of a brain aneurysm early on. Common signs include intense sweaty skin, headaches, dizziness and nausea.
1Other possible signs of a brain aneurysm include;

Sweaty skin
Sweaty skin is a common symptom of many illnesses and ailments, but one condition in particular that can lead to excessive sweating is a brain aneurysm.
When dealing with a brain aneurysm, one of the most common symptoms is profuse sweating or feeling excessively hot or clammy due to increased body temperature. The reason behind this symptom is the increased pressure from the aneurysm on nearby nerves which leads to stimulation of sweat glands and production of sweat for cooling purposes.
