Can Spiders Have Seizures?
WouterIf you’ve ever been bitten by a spider, you may be curious about the possibility of seizures. However, the fact is that most spiders have very little effect on humans.
However, there are some species that can cause a severe reaction to a bite. One of these is the black widow spider. This type of spider is known for its venom, which can cause permanent damage to the nervous system. It can also produce seizures and even paralysis.
Researchers from the University of Queensland have been studying the venom of the funnel-web spider. They discovered that the venom has a unique design.
It’s possible that this venom may help treat Dravet syndrome, a rare and deadly form of epilepsy. Scientists say that a peptide found in the venom called Hm1a can restore the brain’s normal inhibitory transmission and may even be able to cure Dravet syndrome.
Researchers believe that Dravet syndrome is caused by a mutation in a gene called SCN1A. When the mutation occurs, a subunit of fast-spiking inhibitory interneurons is altered. This makes the brain more susceptible to hyperexcitability, which can lead to seizures.
In mice, giving the peptide Hm1a reduced the amount of seizures and epileptiform discharges, as well as rescued the mice from death. Now, researchers are hoping to develop a medication that targets this peptide.
If you or your pet has been bitten by a spider, don’t wait for symptoms to show up. Call a veterinarian immediately. Your veterinarian will monitor your vital signs and prescribe medications, such as muscle relaxants, to relieve pain.
