Brain aneurysm

A cerebral aneurysm is when there is a bulge in a weak area in a wall of an artery that may leak or rupture. A bulging artery puts pressure on the brain tissue or nerves depending on where it is located. If it bursts – or hemorrhages – blood will spill onto the tissue between the brain and the skull. This can lead to hemorrhagic stroke, brain damage or in rare cases, death.

Brain aneurysm causes

Causes and risk factors of a brain aneurysm include:

  • Age – older individuals are more likely to develop aneurysms
  • Excessive alcohol or drug use
  • Family history/genetics
  • Gender – specifically, females are more likely to develop aneurysms
  • High blood pressure
  • Past aneurysms
  • Smoking

Aneurysms can develop after head trauma or infection – but these causes aren’t as common.

Symptoms of aneurysm

In many cases, there will be no visible symptoms of an aneurysm. When symptoms do appear, it is because the brain aneurysm has burst. The symptoms will appear suddenly. Emergency services should be called at 9-1-1 immediately. First-responders are necessary because they may have to use life-saving measures quickly. Symptoms of an aneurysm include:

  • Sudden, severe headaches
  • Blurred vision
  • Changes in speech
  • Neck pain
  • Nausea
  • Sensitivity to light
  • Fainting
  • Seizures

Brain aneurysm treatment and recovery

An unruptured brain aneurysm is normally found during unrelated tests/screenings. A ruptured brain aneurysm will be diagnosed using computerized scans and dye tests. Once a ruptured brain injury is diagnosed, there are a few different treatment options. Doctors will recommend the one(s) best suited to your situation based on factors such as age, location and severity of the aneurysm. These treatment options include:

  • Open surgery which enables the surgeon to place a clip around the base of the aneurysm, preventing blood from entering it
  • Endovascular surgery which happens within the blood vessels. It’s a smaller, less-invasive surgery to implant shunts or coils

Alternatively, doctors may recommend observation and spend more time monitoring the aneurysm.

Coping with changes after a brain aneurysm

A brain aneurysm can have a variety of effects depending on how much blood there is and the damage it does to the brain tissue or other arteries. There can be changes to cognitive and physical abilities, vision, balance, and more. It’s important to keep in mind that treating the brain aneurysm will not reverse the effects it has caused.

That means that once you’re in recovery, you may have to learn new ways to complete activities of daily living (ADLs).

Non-Traumatic Brain Injury (nTBI)

An acquired brain injury (ABI) refers to any damage to the brain that occurs after birth and is not related to a congenital or a degenerative disease. There are two types of acquired brain injury: non-traumatic and traumatic.

Topics in this section include:


Non-traumatic brain injury

Non-traumatic acquired brain injuries are caused by something that happens inside the body, or a substance introduced into the body that damages brain tissues.

This includes:

A video on acquired brain injury

Acquired brain injury affects every part of a person’s life. This includes changes to your independence, abilities, work, and relationships with family, friends, and caregivers. Since a brain injury differs from person to person and recovery depends on several factors, in many cases it’s difficult to know what long-term behavioural, cognitive, physical or emotional effects there will be.

The effects of brain injury can be put in the following categories [1]:

Behavioural changes: The way a person acts or makes decisions can change after a brain injury. Behavioural changes include engaging in risky or impulsive behaviour, having difficulty with social and work relationships and isolation. This can be stressful and depending on the behaviour can cause safety concerns. Rehabilitation and medical teams will be able to provide practical tips for behaviour after a brain injury.

Cognitive changes: This is how the brain learns, processes information, forms memories and makes decisions. Challenges include communication, concentration, reading/writing, making decisions, and remembering things.

Emotional changes: after a brain injury, a person may experience new or different emotions, including depression, anxiety, and/or anger. Emotional changes are difficult to adjust to, and it’s important to have a support system of family, friends, and medical professionals.

Physical changes: In some cases, a brain injury will have physical effects. These effects include mobility challenges, headaches, fatigue, pain and sensory changes.

Is a concussion a brain injury?

A concussion is an acquired brain injury. Anyone who sustains a concussion can experience many of the physical, cognitive, emotional, and behavioural effects that accompany acquired brain injuries.

Concussion is also known as mild traumatic brain injury (mTBI) that has no neuroimaging findings. The term mild does not diminish the impacts that concussion can have on your health and activities of daily living (ADLs).

The challenges of prognosis

Prognosis means the likely path a disease or injury will take. In the case of acquired brain injury, prognosis is meant to give a best estimate of effects and recovery. Acquired brain injuries are all different, and there are a lot of factors that will impact a prognosis of recovery.

Factors that affect prognosis include:

  • Severity of injury
  • Previous injuries and existing conditions
  • Access to treatment
  • Age
  • Location of injury

Research shows that there is no system or set of variables that can accurately predict outcome for a single patient [2]. There is no definite timeline for recovery – it’s different for everyone. Doctors will update their prognosis as recovery progresses and provide next steps at the same time.

This section of our website covers the kinds of changes you may experience, management tips, and information on the kinds of tools and services that can help you and your family navigate living with brain injury.
