Cognitive Abilities and Quality of Life After Cochlear Implantation in the Elderly.

OBJECTIVE: To evaluate quality of life (QoL) and cognitive function in elderly patients with cochlear implants relative to auditory improvement, using geriatric validated scales. STUDY DESIGN: Prospective observational study. SETTING: A tertiary referral center for cochlear implantation (CI) and a geriatric center in Nancy, France. PATIENTS: Sixteen consecutive patients were included, from 65 to 80 years old, with postlingual severe-to-profound deafness. MAIN OUTCOME MEASURES: Evaluations were conducted before and at 6 and 12 months after cochlear implant surgery. A monosyllabic word recognition test was used to measure speech perception. QoL was evaluated by the World Health Organization Quality of Life Assessment for elderly people; cognitive function was evaluated by the Mini-Mental State Examination; depression was evaluated by the Hamilton Scale; autonomy was evaluated by the Instrumental Activities of Daily Living. RESULTS: Speech intelligibility evolved from 10% before surgery to 63% and 69% at 6 and 12 months after cochlear implant activation, respectively. QoL showed significant improvement in sensory abilities. The Mini-Mental State Examination evaluations remained stable and executive functions tended to improve. Autonomy improved significantly. CONCLUSION: Cochlear implantation improves autonomy and the QoL in the elderly. Cognitive functions are not influenced by surgery, but executive functions appear to benefit from implantation. Age should not be a limiting factor, and cochlear implantation can be proposed as an efficient treatment for severe-to-profound hearing loss in the elderly.

Correlations between postural control and psychological factors in vestibular schwannoma patients.

BACKGROUND: Various individual factors have been described to influence postural performances related to vestibular schwannoma. However, psychological factors may also be involved in postural variations. OBJECTIVE: To identify relationships between postural performances, illness perceptions, coping, anxiety-depression and quality of life of patients with vestibular schwannoma. METHODS: Twenty-six patients who were scheduled for a surgical removal of a vestibular schwannoma underwent posturography tests and were asked to complete psychological questionnaires three days prior to surgery.The Sensory Organization Test, the Illness Perceptions Questionnaire-Revised, the Brief-COPE, the Hospital Anxiety Depression Scale and the World Health Organization Quality of Life instrument were used for assessments. Correlations between posturography and psychological questionnaires were calculated. RESULTS: Balance disorders were associated with (i) impaired quality of life of patients, (ii) anxiety and depression affects, (iii) greater daily consequences, and with (iv) denial coping response. CONCLUSIONS: Given the association between balance disorders and psychological factors, health practitioners should be attentive to the deterioration of both aforementioned issues.

Preoperative balance control compensation in patients with a vestibular schwannoma: does tumor size matter?

OBJECTIVE: The influence of tumor size on postural control of patients with vestibular schwannoma (VS) remains to be determined. This study aimed to compare the postural performances of VS patients, according to the size of the tumor, with healthy subjects. METHODS: The six conditions (C1-C6) of the sensory organization test (SOT) were carried out in 87 patients, split into four groups according to the Koos classification (stage I-IV), and in 72 aged-matched controls to evaluate postural control. The vestibular reflectivity and compensation were estimated with videonystagmography. RESULTS: Among patients, lower C5 and C6 scores were found in stage I and IV patients than in stage II and III patients, whereas vestibular compensation did not impact the tumor size influence on the postural control. The scores were significantly (p<0.001) lower for all the groups of patients than the controls in the vestibular-related SOT conditions (C5-C6). CONCLUSIONS: Patients with an unilateral VS displayed altered postural performances compared to the control subjects and tumor size had a bell-like pattern effect on balance control. SIGNIFICANCE: The tumor size could be seen as a determining factor in the implementation of adaptive mechanisms that lead to the postural compensation and might be dissociated from vestibular compensation.
