A Canarsie family is searching for missing loved one who they say suffers from memory loss and seizures.

Cammel Rance Rainey, 44, has been missing for four days.

Rainey's sister, Tamica Davidson, has been putting up posters around her neighborhood on East 101st Street and Flatlands Avenue. She says Rainey suffers from Cadasil syndrome, which affects her brain.

Davidson says her sister often takes walks around the neighborhood but on Tuesday she did not come back. She is concerned that Rainey hasn't taken the medication she urgently needs.

Rainey's family says she was wearing a brown sweater and black pants when she went missing.

Anyone with information on her whereabouts is asked to call police.
