About

Confabulators consistently generate false memories without intention to deceive and with great feeling of rightness. However, there is currently no known effective treatment for them. In order to fill this gap, we performed a neuropsychological treatment in two groups of confabulators: experimental vs. control (ClinicalTrials.gov ID: NCT02540772).

Now, we intend to replicate the treatment with a larger sample of confabulators and with other two control groups: non-confabulator patients with brain injury and healthy individuals

Full description

The treatment consisted of some brief material that patients had to learn and recall at both immediate and delayed moments. After both recollections, patients were given feedback about their performance (errors and correct responses). Pre-treatment and post-treatment measurements were administered.

Non-confabulator patients and healthy participants performed only the pre-treatment measurement.

Enrollment: 57 patients

Sex: All

Ages: 35 to 80 years old

Volunteers: Accepts Healthy Volunteers

• Prior to injury, all patients should be completely independent for daily living.

57 participants in 3 patient groups

Neuropsychological treatment

Experimental group

Description:

The tested treatment is a combination of neuropsychological rehabilitation procedures: learning, episodic memory recall after a delay, selective attention, inhibition of predominant responses and awareness of deficits.

Treatment:

Behavioral: Neuropsychological treatment

Non-confabulators control group

No Intervention group

Description:

Non-confabulators (brain injured patients but without confabulations) in this control group only performed the pre- and post-measurements without treatment.

Healthy control group

No Intervention group

Description:

Healthy participants in this control group only performed the pre- and post-measurements without treatment.
