Quick Scoop: What Happened to Tristan Thompson’s Brother?

Tristan Thompson’s younger brother is Amari Thompson , and he has not “gone missing” or anything like that — the story is about his serious medical condition and Tristan becoming his legal guardian after their mother died.

What actually happened?

  • Amari has a severe form of epilepsy called Lennox–Gastaut syndrome (LGS) , which causes developmental disabilities and difficult-to-control seizures.
  • He is described as severely disabled ; Khloé Kardashian has said he cannot walk or talk and has never been able to talk.
  • In January 2023, Tristan’s mother Andrea Thompson died suddenly from a heart attack, leaving Amari in need of a primary caregiver.
  • Tristan stepped in and was granted temporary guardianship of Amari in September 2023, then became his full legal guardian in early 2024.
  • Since then, Amari has been living with Tristan (and often seen in the orbit of Khloé and the kids), while Tristan balances NBA life and caring for him.

Current situation and “latest news”

  • Tristan has publicly said that caring for Amari and losing their mom completely changed his priorities and perspective on life.
  • He has taken on roles with health and medical‑research projects (like AxonDAO and related ventures) and says his work is inspired by Amari’s condition and the need for better treatment and data around disorders like LGS.
  • Khloé Kardashian has been very involved in Amari’s life, helping with his care and including him in family activities.
  • In late 2025, Khloé called out “gross” online comments criticizing Amari being in dance classes , defending his right to joy and therapy-style activities despite his disabilities.
