She will check the PCV (packed cell volume) in the blood to verify the volume of cells present. The veterinarian may see pupil dilation and clear evidence of external trauma. As previously mentioned, dogs with brain injury may turn in circles when stressed or excited. The veterinarian will begin by assessing the clinical signs of your dog. Complications, for example, hypoxia (deficiency in oxygen), or ischemia (inadequate blood supply) can be life threatening. ICP can lead to changes in the delicate make-up of the brain, blood, and cerebrospinal fluid. Secondary injury - Along with the edema and hemorrhaging of the primary injury, further tissue damage and swelling can result, which in turn causes an increase in intracranial pressure (ICP) and breakdown of the blood-brain barrier (BBB). With the primary injury, care is focused on reducing the effects that can lead to secondary complications.
Vascular tears (tearing of the artery causing reduced blood flow to the brain), and hemorrhaging are included in primary injury. Primary injury - This is the trauma that occurs at the time of impact and results in a physical disruption of intracranial structures. Injuries to the brain are broken down into two categories:
There is a loss in control of movements of the body (ataxia).Your dog is circling over and over, especially when excited or facing stress.As in the case of any behavioral change in your pet, the following signs mean a veterinarian visit is crucial: In the event of a circumstance that you did not see occur, recognition of all signs could be difficult. Of course, in the case of a traumatic accident that you may have witnessed such as a fall or impact, you will be aware that the demeanor of your pet is resulting from the incident. The signs of brain injury can easily range from really obvious to not so clear or apparent.
