Getting To The Other Side: An Exploration Of The Head And Neck Cancer Treatment Experience, Heather M. Wallace

Theses and Dissertations--Gerontology

Diagnosis of head and neck squamous cell carcinoma (HNSCC) presents a multifarious problem. Late stage diagnosis, uncertainty regarding appropriate clinical treatment, as well as the high potential for disfigurement and functional loss resulting in diminished quality of life, contributes to anxiety, stress, fear, and uncertainty throughout the cancer treatment experience. This qualitative study sought to explore the cancer treatment experience of adults with newly diagnosed HNSCC, including laryngeal, esophageal, and oral cancers. Study participants were recruited from the University of Kentucky Ear Nose and Throat Clinic in Lexington KY. Participants agreed to be interviewed after receipt of their cancer diagnosis …

Memory, Cognition, And The Effect Of A Music Intervention On Healthy Older Adults, Shannon L. Bowles

Theses and Dissertations--Gerontology

Music is a powerful modality that can bring about changes in individuals of all ages. This research employed both an experimental and quasi-experimental design to identify the effects of music as it influenced psychological well-being, memory, and cognition among older adults. Specifically, it addressed three aims: (a) To determine to what extent learning to play a music instrument later in life influenced psychological well-being and cognitive function of non-institutionalized healthy seniors, (b) To determine the effects of the amount of music involvement on psychological well-being and cognitive function (c) To determine the benefit of music for those with limited/no music …

Effects Of Intranasally Administered Dnsp-11 On The Central Dopamine System Of Normal And Parkinsonian Fischer 344 Rats, James H. Sonne

Theses and Dissertations--Neuroscience

Due to the blood-brain barrier, delivery of many drugs to the brain has required intracranial surgery which is prone to complication. Here we show that Dopamine Neuron Stimulating Peptide 11 (DNSP-11), following non-invasive intranasal administration, protects dopaminergic neurons from a lesion model of Parkinson’s disease in the rat. A significant and dose-dependent increase in an index of dopamine turnover (the ratio of DOPAC to dopamine) was observed in the striatum of normal young adult Fischer 344 rats by whole-tissue neurochemistry compared to vehicle administered controls.

Among animals challenged with a moderate, unilateral 6-hydroxy-dopamine (6-OHDA) lesion of the substantia nigra, those …

Changes In Sleep Architecture And Cognition With Age And Psychosocial Stress: A Study In Fischer 344 Rats, Heather M. Buechel

Theses and Dissertations--Pharmacology and Nutritional Sciences

Changes in both sleep architecture and cognition are common with age. Typically these changes have a negative connotation: sleep fragmentation, insomnia, and deep sleep loss as well as forgetfulness, lack of focus, and even dementia and Alzheimer’s disease. Research has shown that psychosocial stressors, such as isolation from family and friends or loss of a loved one can also have significant negative effects on sleep architecture and cognitive capabilities. This leaves the elderly in a particularly vulnerable situation: suffering from cognitive decline and sleep dysregulation already, and more likely to respond negatively to psychosocial stressors. Taking all of these factors …
