Parenting at a Challenging Time (PACT)

The ALS PACT Program aims to support parents and coparents in addressing the disease-related challenges faced by their children (infants through young adults). A child psychologist or psychiatrist meets privately with parents to understand their children’s unique strengths and needs, and to provide ongoing developmental guidance and support throughout the family’s journey with ALS.
