Diseases of the brain

Diseases of the brain


The symptoms of brain diseases are usually the same, despite different causes.

The following are possible causes of central nervous disorders:

  • Infections of the brain caused by viruses, bacteria, mycoplasma, parasites and other pathogens.
  • Toxins, such as lead, nicotine, table salt, zinc and caffeine.
  • Organ diseases, such as liver damage or kidney disease.
  • Brain injuries after accidents (e.g. collision with window pane)
  • Circulatory disorders, such as cardiovascular disease.
  • Deficiencies, such as the lack of vitamin B or calcium.
  • Tumors in the brain.


The following symptoms may occur with central nervous disorders:

  • Coordination and balance problems, such as falling off the pole or missing landing spots during free flight.
  • Twisting the head, turning the neck 180°, turning the bird around its own axis or walking in circles.
  • Seizures, with the bird suddenly falling from the perch, fidgeting, flapping its wings and making unusual sounds.
  • Disturbances of consciousness, such as drowsiness and loss of consciousness.


Since budgies are particularly vulnerable to shock, the vet must also proceed calmly and with the utmost caution.

Further treatment of the bird will then depend on the cause identified:

  • Administration of vitamin B or calcium in case of deficiencies
  • Antibiotics for infections with bacteria
  • etc.

It is imperative that budgies with central nervous disorders be kept quiet. For this purpose, it is advisable to place it on a soft surface in a darkened room.

No heat treatment!

In case of brain diseases, do not apply heat radiation, as it would worsen the condition of the budgie.
