Given an abstract of a paper, generate a title for this paper such that conveys the key focus of the paper.

Example input: Abstract: Some patients converted from ventricular fibrillation to organized rhythms by defibrillation-trained ambulance technicians (EMT-Ds) will refibrillate before hospital arrival. The authors analyzed 271 cases of ventricular fibrillation managed by EMT-Ds working without paramedic back-up. Of 111 patients initially converted to organized rhythms, 19 (17%) refibrillated, 11 (58%) of whom were reconverted to perfusing rhythms, including nine of 11 (82%) who had spontaneous pulses prior to refibrillation. Among patients initially converted to organized rhythms, hospital admission rates were lower for patients who refibrillated than for patients who did not(53% versus 76%, P = NS), although discharge rates were virtually identical (37% and 35%, respectively). Scene-to-hospital transport times were not predictively associated with either the frequency of refibrillation or patient outcome. Defibrillation-trained EMTs can effectively manage refibrillation with additional shocks and are not at a significant disadvantage when paramedic back-up is not available.
Example output: Refibrillation managed by EMT-Ds
Example explanation: The abstract is about refibrillation and it is also mentioned in the abstract that it is managed by EMT-Ds. So it is an apt title.
Q: Abstract: This study investigates the hypothesis that, as a consequence of Parkinson's disease, disturbed caudate outflow will lead to deficits in cognitive functions dependent upon the integrity of the prefrontal cortex, the cortical focus of caudatofugal signals. Since Parkinson's disease also involves lesions in extra-striatal midbrain cells which reduce the extrinsic supply of dopamine to this cortical region, such functions are at double risk. Forty nondemented parkinsonian patients were drawn from a pool of 100 consecutive patients and matched with 40 normal control subjects according to age, education, IQ, and sex. All patients were quantitatively rated on neurological indices of disease. Neuropsychological assessment of the patient and normal groups included tests of general intelligence, psychomotor skills, memory, visuospatial and executive functions. No global cognitive decline was observed in the parkinsonian group. Moreover, memory and visuospatial abilities were generally intact. A small cluster of deficits emerged, interpreted as reflecting impairment in the ability to spontaneously generate efficient strategies when relying on self-directed task-specific planning. In addition, several tests thought to be sensitive to frontal lobe function distinguished patients with symptoms strongly lateralized to the right versus left side of the body. Deficits in strategic planning were later investigated in relation to severity of disease and to patient attributes including IQ and age, both of which were relevant to performance on specific tasks. Results were compared with previous investigations in parkinsonian patients and discussed from the perspective of both animal and human studies involving damage to the cerebral cortex and basal ganglia. As the prefrontal cortex is thought to play a crucial role in self-directed behavioural planning, the validity of an outflow model in predicting the consequences of caudate nucleus dysfunction was supported.
