Atherosclerosis is the build-up of plaque in the arteries, which can narrow the arteries and reduce blood flow to the brain. This can cause a stroke if the blood supply to the brain is suddenly cut off.
2. Blood clots
Blood clots can form in the arteries or veins in the brain, blocking blood flow and causing a stroke. Blood clots can be caused by a variety of factors, including:
* Heart disease
* High blood pressure
* Diabetes
* Smoking
* Obesity
* Certain medications
* Family history of stroke
3. Vasculitis
Vasculitis is a condition that causes inflammation of the blood vessels. This inflammation can damage the blood vessels and make them more likely to develop blood clots. Vasculitis can be caused by a variety of factors, including:
* Autoimmune disorders
* Infections
* Certain medications
* Cancer
4. Arteriovenous malformations (AVMs)
AVMs are abnormal connections between arteries and veins. These connections can allow blood to flow directly from the arteries into the veins, bypassing the capillaries. This can cause the blood pressure in the arteries to increase and the blood flow to the brain to decrease. AVMs can be present at birth or they can develop later in life.
5. Head trauma
Head trauma can damage the blood vessels in the brain and cause a stroke. Head trauma can be caused by a variety of accidents, including:
* Car accidents
* Falls
* Sports injuries
* Assaults
6. Certain medical conditions
Certain medical conditions can increase the risk of stroke in young budgies, including:
* Sickle cell disease
* Leukemia
* Polycythemia vera
* Thrombocytopenia
* Protein C deficiency
* Protein S deficiency
* Antithrombin III deficiency
If you think your young budgie may be having a stroke, it is important to take them to the vet immediately. Early diagnosis and treatment can improve the chances of a full recovery.
