Valenza umana della cura (care) dei pazienti in SVP e ruolo dei caregivers
2016
[Human value of care and caregivers' role in the management of permanent vegetative state (SVP) patients] As stated by the Royal College of Physicians, «patients who remain in a vegetative or minimally conscious state following profound brain injury present a complex array of clinical and ethical challenges to those who care for them». Patients in clinical condition of Permanent Vegetative State (SVP) are unaware of self and environment, enable of language comprehension or expression; they are able to survive along provided that we are able to ensure primary care, such as eating and hydration. With regard to this existential landmark, caregiver’s role is not only legally related, as guardia…
Locked-in Syndrome and 18F-fluorodeoxyglucose-positron Emission Tomography/Computed Tomography: Observations from a Case of Basilar Artery Thrombosis
2018
We report the case of a 59-year-old male patient suffering from locked-in syndrome (LIS) following basilar artery thrombosis despite an attempt of thrombolysis. Neurological examination showed quadriplegia and aphonia and a state of coma requiring mechanical ventilation was diagnosed. The use of 18F-fluorodeoxyglucose (18F-FDG)-positron emission tomography (PET) allowed to detect a normal 18F-FDG uptake in the main cerebral cortical areas and a significant reduction of 18F-FDG uptake in both cerebellar hemispheres, compatible with a functional deafferentation, helping confirming the clinical suspicion of LIS. The diagnosis of LIS, according to literature, is based on the clinical assessment…
How brain-computer interface technology may improve the diagnosis of the disorders of consciousness: A comparative study
2022
ObjectiveClinical assessment of consciousness relies on behavioural assessments, which have several limitations. Hence, disorder of consciousness (DOC) patients are often misdiagnosed. In this work, we aimed to compare the repetitive assessment of consciousness performed with a clinical behavioural and a Brain-Computer Interface (BCI) approach.Materials and methodsFor 7 weeks, sixteen DOC patients participated in weekly evaluations using both the Coma Recovery Scale-Revised (CRS-R) and a vibrotactile P300 BCI paradigm. To use the BCI, patients had to perform an active mental task that required detecting specific stimuli while ignoring other stimuli. We analysed the reliability and the effic…
