Tyler Henry has another big update for concerned fans! The Hollywood Medium star has been recovering from an emergency brain surgery, and he worried fans last week when he shared an update on his healing. While revealing his memory is "improving," he shared that he can now "hold on to about 10 minutes of short term memory." Wow! SO intense and scary!!! This was his third brain surgery over the years and came after he last went under the knife in May for a planned operation to remove a cyst on his brain.
