A woman has a rare condition which causes her to laugh uncontrollably.
Becca Banks, from Runcorn, started to experience what her family described as "strange episodes" around three and half years ago. Doctors initially diagnosed her with anxiety and depression and the 35-year-old was put on medication for this for 18 months.
However, the 35-year-old questioned her initial diagnosis and went to seek an alternative opinion privately. Sister-in-law Jean Stone, 40, said Becca suffered epilepsy as a child and was diagnosed at around seven years old, but "grew out" of this around the age of 16.
