  1. 1. Sex Differences in Dopamine D1-type Receptors and Episodic Memory : an Imaging Study Across the Adult Lifespan

    Master-uppsats, Umeå universitet/Umeå centrum för funktionell hjärnavbildning (UFBI); Umeå universitet/Institutionen för psykologi

    Författare :Anton Degerfält; [2023]
    Nyckelord :dopamine; D1DR; sex; episodic memory; ageing; PET; MRI;

    Sammanfattning : Identification of the pathways that could be targeted to alleviate ageing-related cognitive decline is of prime importance. One of the most promising target mechanisms is connected to healthy dopaminergic ageing. LÄS MER

  3. 2. The impact of prebiotics, probiotics, and synbiotics on mild cognitive impairment : a systematic review

    Kandidat-uppsats, Örebro universitet/Institutionen för medicinska vetenskaper

    Författare :Astrid Viktorsson; Noah Westerholm; [2023]
    Nyckelord :MCI; Mild cognitive Impairment; Prebiotics; Probiotics; Synbiotics; DW2009; Bifidobacterium Breve A1; RBANS; MMSE.;

    Sammanfattning : Background: Mild Cognitive Impairment (MCI) is seen as a state between normal aging and dementia, with patients having an increased risk of developing Alzheimer’s disease (AD) and other sorts of dementia. MCI has been linked to a change in gut microbiota which impacts the microbiota-gut-brain axis (MGBA), consequently affecting neurological functions. LÄS MER

  4. 3. Predictive MR Image Generation for Alzheimer’s Disease and Normal Aging Using Diffeomorphic Registration

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Yuqi Zheng; [2023]
    Nyckelord :Medical Image Generation; Brain Aging; Diffeomorphic Registration; AlzheimerŠs Disease; Medicinsk bildgenerering; Åldrande av hjärnan; DiffeomorĄsk registrering; Alzheimers sjukdom;

    Sammanfattning : Alzheimer´s Disease (AD) is the most prevalent cause of dementia, signifying a progressive and degenerative brain disorder that causes cognitive function deterioration including memory loss, communication difficulties, impaired judgment, and changes in behavior and personality. Compared to normal aging, AD introduces more profound cognitive impairments and brain morphology changes. LÄS MER

  5. 4. Understanding subjective measures of olfaction and cognition : A study on the occurrence of subjective olfactory and/or cognitive decline and their effect on future behavioral performance

    Master-uppsats, Stockholms universitet/Kognitiv psykologi

    Författare :Andrea Aejmelaeus-Lindström; [2022]
    Nyckelord :subjective olfactory decline; subjective cognitive decline; olfaction; anosmia; cognition; aging;

    Sammanfattning : Dementia is a growing burden for society, and it is of interest to discover it at an early stage. Both subjective cognitive decline (SCD) and subjective olfactory decline (SOD) has been associated with future cognitive decline and dementia. However, subjective measures have often been criticized and are still not fully understood. LÄS MER

  7. 5. Investigating the relationship between dementia and cognitive tests performance : do better scores on cognitive tests relate to a lower risk of developing dementia?

    Kandidat-uppsats, Umeå universitet/Statistik

    Författare :Emma Kwon; Markus Lindvall; [2022]
    Nyckelord :;

    Sammanfattning : In 2021, dementia was the seventh leading cause of death among all diseases in the world according to the World Health Organization (2021). Dementia is an overall medical term indicating deteriorated brain health associated with loss of memory, cognitive abnormality and difficulties in daily activities. There is no medical cure for dementia yet. LÄS MER
