  1. 26. Attention-Deficit/Hyperactivity Disorder (ADHD) Beyond the Young Age : Investigation of the Prevalence of ADHD in Older Adults and the Risk of Age-related Disorders

    Författare :Maja Dobrosavljevic; Henrik Larsson; Ebba du Rietz; Henrik Andershed; Alexandra Philipsen; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ADHD; prevalence; comorbidity; functional impairments; older adults; age-related disorders; dementia; mild cognitive impairment; cardiometabolic disorders; prediction model;

    Sammanfattning : Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder characterized by impairing levels of inattention and/or hyperactivity-impulsivity. Symptoms of ADHD, which typically emerge in childhood, may persist until older age with a substantial adverse impact on health and functionality. LÄS MER

  2. 27. Massive Multi-Antenna Communications with Low-Resolution Data Converters

    Författare :Sven Jacobsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; orthogonal frequency-division multiplexing; channel estimation; quantization; linear precoding; convex optimization; nonlinear precoding; linear combing; hardware impairments; analog-to-digital converter; beamforming; Massive multi-user multiple-input multiple-output; digital-to-analog converter;

    Sammanfattning : Massive multi-user (MU) multiple-input multiple-output (MIMO) will be a core technology in future cellular communication systems. In massive MU-MIMO systems, the number of antennas at the base station (BS) is scaled up by several orders of magnitude compared to traditional multi-antenna systems with the goals of enabling large gains in capacity and energy efficiency.

  3. 28. Older drivers with cognitive impairments : issues of detection and assessment

    Författare :Catarina Lundberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Older drivers; cognitive impairment; preclinical dementia; cognitive assessment; driving test;

    Sammanfattning : Older drivers are often presented as a traffic safety problem. Age-related medical conditions such as dementias and stroke impair cognitive functions that are crucial for safe driving. Uncertainty remains regarding the most appropriate clinical methods to assess driving fitness in these patient groups. LÄS MER

  4. 29. Visual, musculoskeletal, and balance symptoms in people with visual impairments

    Författare :Christina Zetterlund; Lars-Olov Lundqvist; Hans O. Richter; Tony Pansell; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Visual impairment; musculoskeletal symptoms; balance symptoms; visual enhancing aids; age-matched controls; Surgery; Kirurgi;

    Sammanfattning : Background: Worldwide, about 300 million people have some kind of visual impairment (VI). Most people with VI are in the older age range, as visual deficits increase with age. It is not unusual that people with VI suffer both from neck pain or scapular area symptoms and reduced balance, which they consider to be symptoms of old age. LÄS MER

  5. 30. Physical performance tests and spinal pain : assessing impairments and activity limitations

    Författare :Therese Ljungquist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Back pain; decision-making; disability evaluation; low-back pain; methods motor skills; neck pain; needs assessment; outcome assessment; pain measurement physical therapy; reproducibility of results.;

    Sammanfattning : Background: Long-term spinal pain is a common health problem, often leading to disabilities. There is still no general agreement on what measures to use for evaluating disability in people with spinal pain. LÄS MER
