Five-year follow-up study of patients with persistent vegetative state
Journal of Neurology, Neurosurgery, and Psychiatry
|June 1, 1981
Summary
Most patients in a persistent vegetative state (PVS) do not recover. Of those who partially recover, few regain communication or independence, highlighting the long-term challenges of PVS.
Area of Science:
- Neurology
- Neuroscience
- Clinical Medicine
Background:
- Persistent Vegetative State (PVS) presents significant challenges in predicting patient outcomes.
- Understanding long-term prognosis is crucial for patient care and resource allocation.
Purpose of the Study:
- To investigate the long-term outcomes and recovery rates of patients diagnosed with persistent vegetative state.
- To analyze survival rates, partial recovery, and functional independence in a cohort of PVS patients.
Main Methods:
- A longitudinal study followed 110 patients with PVS over a five-year period (1973-1978).
- Data collection included mortality, partial recovery, communication ability, and daily activity independence.
- Clinical symptoms and reactivity of 30 survivors were monitored.
Main Results:
- A high mortality rate of 73% was observed within the five-year follow-up period.
- Approximately 10% of patients experienced partial recovery from the vegetative state.
- Among recovered patients, only three could communicate, and two remained dependent for daily activities.
Conclusions:
- Recovery from persistent vegetative state is rare, with limited functional gains even in partially recovered individuals.
- The long-term prognosis for PVS patients is generally poor, emphasizing the need for supportive care.
- Minimal changes in reactivity and symptoms were noted in survivors over the final two years of observation.
