The blood required by the brain is channeled through four blood vessels through the neck to succeed in the brain. Aneurysms usually occur in weak blood vessels.</p>
<p>The exact cause behind the weakening of the vessel wall can not be discovered. However, many factors area unit thought to weaken the walls of the blood vessels and trigger brain aneurysms. These factors include:</p>
<p>High pressure level. This condition will increase the pressure on the walls of blood vessels that triggers brain aneurysms. High pressure level is vulnerable to fleshiness or an excessive amount of salt, alkaloid and alcohol.</p>
<p>Age higher than forty years. Brain aneurysms area unit additional common in folks over the age of forty. this is often thanks to the condition of the vessel wall that weakens over time thanks to pressure level passing through the wall.</p>
<p>Female sex. the majority with brain aneurysms area unit ladies. this is often thought to be associated with a decrease in oestrogen that maintains the physical property of blood vessels. This decline typically happens once climacteric.</p>
<p>Head injury. though rare, severe injury to the brain will increase the danger of brain aneurysms.</p>
<p>Alcohol consumption and abuse (especially cocaine).</p>
<p>Non-congenital medical conditions, like sure blood infections, induration of the arteries (hardening of the arteries), and shrivelled levels of biological time internal secretion|steroid|sex hormone} hormone.</p>
<p>Congenital medical conditions, like polycystic nephropathy, coarctation of the arterial blood vessel, arterial-venous malformations, and disturbances in body tissues (for example within the case of Ehlers-Danlos syndrome and Marfan syndrome).</p>
<p>History of brain cardiovascular disease within the family.</p>
