Bipolar Disorder (BD) and Schizoaffective Disorder (SA) clients.

  • determine if after 12 months of treatment with clozapine, the BMI changes with clients who are councelled as usual regarding weight gain while on Clozapine.
  • determine if after 12 months of treatment with clozapine, the BMI changes with intense, structured councelling about diet and exercise.

Condition or disease Intervention/treatment

Detailed Description:
To determine whether the changes in BMI produced in subjects with Bipolar Disorder (BD) and Schizoaffective Disorder (SA) by 12 months of treatment with clozapine, can be diminished after an intense and highly structured intervention focused on diet and exercise, compared with the usual brief counseling regarding weight gain on this drug.

Drug Information available for: Clozapine

Group/Cohort Intervention/treatment
Counselling as Usual
Discussing Clozapine medication, diet and exercise as per clinical protocol potential weight changes
Behavioral: Counselling as Usual
5 - 20 minutes, about the effects of clozapine on body weight, appetite, blood sugar and fats such as cholesterol and triglycerides in the blood, and how these might affect your health in the future.

Cognitive Behavoural Therapy
Counselling about Clozapine medication, diet and exercise in a structured fashion using Cognitive Behavioural Therapy about potential weight changes
Behavioral: CBT
45 - 60 minutes individual treatment sessions focused on nutrition, exercise and weight control and will occur weekly for 4 weeks. After this, 10 group sessions focused on weight reduction will be held every 2 weeks. This will be followed by 6 group sessions focused on weight maintenance held every 2 weeks.

Primary Outcome Measures :
  1. Increases in BMI in subjects with BD and SA after 12 months of clozapine treatment will be smaller in subjects treated with CBT ex/diet compared with those receiving CAU. [ Time Frame: 5 years ]

Secondary Outcome Measures :
  1. Adverse changes in plasma lipids, blood sugar, and fitness level will be greater in subjects treated with CBT ex/diet compared with those receiving CAU after 12 months of clozapine treatment. [ Time Frame: 5 years ]
