leukopenia
lymphopenia
neutropenia
thrombocytopeniaOther signs include: fever, loss of skin elasticity due to dehydration, abdominal pain, sternal recumbency with splayed legs and head droop, nasal discharge and conjunctivitis. Cats may sit at a water bowl, but not drink. Terminal cases are hypothermic and may develop septic shock and disseminated intravascular coagulation.Infection in pregnant cats can result in fetal resorption, mummification, abortion, or stillbirth of neonates. Fetuses infected in utero that survive and kittens less than a few weeks of age that become infected can have cerebellar hypoplasia, retinal dysplasia, and optic neuropathy. Diagnosis
A presumptive clinical diagnosis of FPLV can be made for kittens with appropriate signalment, history, clinical findings and the history of no prior vaccination.The clinical diagnosis is usually supported by documenting parvovirus antigen in feces by ELISA (enzyme-linked immunosorbent assay) and PCR (polymerase chain reaction) assays. The availability of validated assays varies by country but is becoming more common. PCR assays are so sensitive that FPV DNA can be amplified from feces of cats vaccinated with modified live strains of the virus. At least one of the ELISA antigen tests for dogs (SNAP®Parvo; IDEXX Laboratories) detects FPV in feline feces and has a cut point for a positive test result that excludes most vaccinated cats. Thus, this ELISA is superior to PCR for screening cats for FPV infection and can also be performed in the veterinary clinic. (These are only approved and licensed for detecting canine parvovirus, but it is generally known that they also detect FPL viral antigen in feline feces.
There are also reports of significantly improved consciousness in patients treated for non-traumatic cases of DoC, such as in the case of a subarachnoid hemorrhage, cerebral hemorrhage, and hypoxic encephalopathy. In 2018 the American Academy of Neurology (AAN) updated treatment guidelines on the use of amantadine for patients with prolonged DoC, recommending the use of amantadine (100–200 mg bid) for adults with DoC 4–16 weeks post injury to support early functional recovery and reduce disability. Neuroplasticity and overall functional recovery in patients with brain injury
In various studies, amantadine and memantine have been shown to accelerate the rate of recovery from a brain injury. The time-limited window following a brain injury is characterized by neuroplasticity, or the capacity of neurons in the brain to adapt and compensate after injury. Thus, physiatrists will often start patients on amantadine as soon as impairments are recognized. There are also case reports showing improved functional recovery with amantadine treatment occurring years after the initial brain injury. There is insufficient evidence to determine if the functional gains are a result of effects through the dopamine or norepinephrine pathways. Some patients may benefit from direct dopamine stimulation with amantadine, while others may benefit more from other stimulants that act more on the norepinephrine pathway, such as methylphenidate. It is unclear if treatment with amantadine improves long-term outcomes or simply accelerates recovery. Nonetheless, amantadine-induced acceleration of recovery reduces the burden of disability, lessens health care costs, and minimizes psychosocial stressors in patients. Adverse effects
Amantadine is generally well tolerated and has a mild side-effect profile.
