2. 1. Mild Traumatic Brain Injury : Studies on outcome and prognostic factors

   Author : Marianne Lannsjö; Jörgen Borg; Per Enblad; Ulla Johansson; Richard Levi; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rehabilitation; Mild Traumatic Brain Injury; Rivermead Post-concussion Symptoms Questionnaire; Rasch-analysis; prediction; outcome; head CT pathology; Magnet Resonance Imaging; Rehabilitation Medicine; Rehabiliteringsmedicin;

   Abstract : Objectives: To explore the prevalence and structure of self-reported disability after mild traumatic brain injury and the impact of traumatic brain pathology on such outcome.Material and methods: In study 1-3, symptoms data were collected by use of Rivermead Post-concussion Symptoms Questionnaire (RPQ) and data on global function by use of Glasgow Outcome Scale Extended (GOSE) from 2602 patients at 3 months after MTBI.

4. 2. Human brain function evaluated with rCBF-SPECT : memory and pain related changes and new diagnostic possibilities in Alzheimer’s disease

   Author : Torbjörn Sundström; Katrine Riklund; Rimma Danielsson; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; brain imaging; rCBF; SPECT; early diagnosis; brain atlas; HMPAO; Alzheimer´s disease; Whiplash; neuropsychological function; episodic memory; Diagnostic radiology; Diagnostisk radiologi;

   Abstract : The aim of this doctoral thesis was to study the influence of memory, pain, age and education on the regional cerebral blood flow (rCBF), i.e. brain function, in early Alzheimer's disease (AD) and in chronic neck pain patients in comparison to healthy controls and in healthy elderly per se.

5. 3. Deriving biomarkers from computed tomography using deep learning

   Author : Meera Srikrishna; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CT; MRI; convoluted neural networks; deep learning; Dementia; Alzheimer s disease; Normal pressure hydrocephalus; brain segmentation;

   Abstract : X-ray computed tomography (CT) and magnetic resonance imaging (MRI) are widely used structural neuroimaging modalities. For brain atrophy assessment and volumetric quantification using automated methods, MRI is the preferred modality due to its superior soft tissue contrast. READ MORE

6. 4. Severe traumatic brain injury : clinical course and prognostic factors

   Author : Maud Stenberg; Britt-Marie Stålnacke; Richard Levi; Jan Lexell; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Severe traumatic brain injury; outcome; rehabilitation; prognosis; rehabiliteringsmedicin; Rehabilitation Medicine;

   Abstract : Traumatic brain injury (TBI) constitutes a major health problem and is a leading cause of long-term disability and death. Patients with severe traumatic brain injury, S-TBI, comprise a heterogeneous group with varying complexity and prognosis. READ MORE

7. 5. Machine learning for identification of brain activity patterns with applications in gentle touch processing

   Author : Malin Björnsdotter Åberg; Göteborgs universitet; []
   Keywords : Somatosensory; Machine learning; Pattern recognition; fMRI; Support vector machines; Neuroscience; Brain; BOLD; Signal processing; Artificial intelligence; Touch; Human; Unmyelinated; Sensory; Affective;

   Abstract : Since the first mention of artificial intelligence in the 1950s, the field of machine learning has provided increasingly appealing tools for recognition of otherwise unintelligible pattern representations in complex data structures. Human brain activity, acquired using functional magnetic resonance imaging (fMRI), is a prime example of such complex data where the utility of pattern recognition has been demonstrated in a wide range of studies recently (Haynes et al.
