A woman says that Botox treatments caused her brain damage, giving her autoimmune encephalitis movement disorder, dementia, and other problems.

According to Cynthia Vandenboom, her doctors recommended two series of Botox injections to treat a head tremor. After undergoing the treatment, she had widespread rashes, fever, vomiting, and mental confusion. Vandenboom also had severe back pains, neck pains, and headaches.

Apart from developing autoimmune encephalitis movement disorder, she also experienced deteriorating cognitive functions and difficulties in walking.

“Previously an articulate and high-functioning individual,” explains Vandenboom, “she is now dependent on others for many activities of daily living.”

Vandenboom says she has a difficult time reading and often falls. She is suing Allergan in the City Court, accusing the Botox maker of making a product that’s more dangerous than cyanide. Furthermore, Vandenboom believes that Allergan does not issue enough warnings about the anti-wrinkle drug to consumers.

According to Vandenboom, Botox can spread outside of the injected area, causing critical brain responses.

She is seeking $10million in compensatory damages and $1million for punitive damages.
