Botulinum Toxin (Botox) Injections

What is a Botulinum Toxin (Botox) Injection?

Botulinum toxin is a neurotoxin that is produced by the bacterium responsible for botulism, Clostridium botulinum.  The neurotoxin works by weakening the muscles and stopping them from contracting very well, which can lead to paralysis.  While the commercial medical drug is a purified form of this toxin, it helps with many neurological conditions due to muscles being too tight or overcontracted.

Why did the Clinician order this exam/study?

Dr. Dave Hogarty will use an injection of Botulinum Toxin to treat two major issues:

  1. Spasticity which is a condition that causes muscles to be tight and painful, which limits function. It is commonly due to having a stroke or cerebral palsy.  Botox injections can help loosen muscles for up to 3 months, resulting in better function (such as improved walking) and decreased pain.  The treatment effects last for 3 months, and then a repeat injection is performed if the medication is helpful.
  2. Migraine headaches. Smaller doses of Botox are injected into muscles of the forehead and scalp.  This is reserved for patients who have severe migraines and have not responded to more conventional treatments.
