INCB Criteria of Patiens selection

• Diagnosis by the referral psychiatrist• Control and agreement on the diagnosis

by two indipendent psychiatrist

• Neuroradiological studies

• Team ( psychiatrist, neurologist, neurosurgeons) discussion and agreement

• Informed consensus to surgery ( patient , family or legal tutor)

Somatoform Disorders Common Characteristics

Disorders in this category include those where the symptoms suggest

a medical condition but where no medical condition can be found by a physician.

In other words, a person with a somatoform disorder might experience significant pain without

a medical or biological cause, or they may constantly experience minor aches

and pains without any reason for these pains to exist.

Somatoform Disorders

PrognosisPoor. The course is typically chronic and persists for years, and often involves other symptoms such as depression, anxiety, and drug abuse.

ATYPICAL FACIAL PAIN

60 years female patient

More than 10 years of chronic pain of the face perioral area

Refractory to any kind of drugs treatment including opioids ,neuroleptics ,antiepileptics etc..

No social life , completely invalidated

After four months of high frequency stimulation of the Cingulate cortex (Brodman area 24) the patient became

pain free

At 3 year, follow-up still control of pain, that became episodic instaed of continous

VNS For Depressive Disorder

VNS SURGERY

VNS:VNS:

Modification of regional functional anatomy Modification of regional functional anatomy

Main conceptual benchmarks in the genesis of depression:

- imbalance in the prefrontal-limbic circuit

-VNS could modify such balance

Functional Magnetic Resonance (fMRI) may evidence the immediate effects of VNS

SPECT and PET may evidence long-term effects

PET STUDIES

74 European patients with therapy-resistant major depressive disorder. Psychometric measures were obtained after 3, 12, and 24 months of VNS.

Journal of Clinical Psychopharmacology & Volume 30, Number 3, June 2010

Mixed-model repeated-measures analysis of variance revealed a significant reduction (P ≤ 0.05) at all the 3 time points in the 28-item Hamilton Rating Scale for Depression (HRSD28) score

•53.1% (26/49) of the patients fulfilled the response criteria (Q50% reduction in the HRSD28 scores from baseline)

• 38.9% (19/49) fulfilled the remission criteria(HRSD28 scores e 10).

From January 2004 to November 2006 fourteen patients with TRD From January 2004 to November 2006 fourteen patients with TRD (age 43 to 80; ten men and four women) underwent VNS(age 43 to 80; ten men and four women) underwent VNS

• Baseline scores: ≥ 20≥ 20 on HDRS21.

• All of them had failed at least four antidepressant trialsfour antidepressant trials in their current major depressive episode

3. They did not benefit from a minimum of 6 months6 months of psychotherapy and their current episode was lasting for at least two years.at least two years.
