2012 (English)Doctoral thesis, comprehensive summary (Other academic)
Abstract [en]

The aim of this thesis was to describe the medical, cognitive and psychosocial consequences of epilepsy in young adulthood. Four studies were carried out with this patient group. The first two papers were based on a follow-up study regarding young adults with epilepsy that investigated medical and psychosocial aspects and compared the present results with those five years earlier. We then conducted focus group interviews with young adults with epilepsy and subjective cognitive decline to assess the deeper meaning of living with epilepsy accompanied by cognitive difficulties. In the fourth study we studied cognitive dysfunction further, choosing the language function in young adults with epilepsy. We firstly examined whether language impairments were associated to functional brain alterations and secondly related the language performance to demographics, clinical data, Quality of Life (QoL) and self-esteem.

The five-year follow up of 97 young adults with uncomplicated epilepsy revealed no improvement regarding seizure frequency or side effects from anti-epileptic drugs (AEDs) over time, even though many new-generation AEDs had been established during this period. During the study period 21% had recovered from epilepsy, Seizure frequency among those who still had epilepsy had not improved, and 42% had experienced seizures during the past year. New-generation anti-epileptic drugs (AEDs) had been introduced to PWE, especially to women. There is still need for new and more effective treatment options for this group in the future. It is essential to find alternative approaches to develop better treatment options for this group in the future. However QoL was normal compared to the general population, indicating that new options regarding treatment can have made an impact. Lower QoL was correlated to high seizure frequency and to cognitive side effects. Self-esteem and Sence of Coherence were impaired compared to the situation at adolescence. Self-esteem was correlated to seizure frequency and to side-effects of antiepileptic drugs. Sence of Coherence was not correlated to epilepsy-related factors in the same way as QoL, but mirrored the phenomenon of epilepsy.

The qualitative study showed that the consequences of epilepsy are not only restricted to the consequences of seizures, but also concerns many other aspects of life. The interviews revealed four themes: “affecting the whole person“, “influencing daily life”, ”affecting relations” and ”meeting ignorance in society”. Another important factor was language function; when one loses some language ability, this gives a feeling of losing one’s capability.

The fourth study examined language by neuropsychological methods and correlated this function to brain activation measured by fMRI. Language functions measured in verbal fluency and abstract language comprehension were impaired in participants with both generalized epilepsy and epilepsy of focal onset. Age at onset of epilepsy and education are the most important factors correlating to language function. An additional factor that impacts abstract language comprehension is the frequency of convulsive seizures, while use of topiramate /zonisamide affect verbal fluency negatively. QoL was not correlated to language impairments, but for patients with focal onset seizures there was a correlation between self-esteem and abstract language comprehension. The fMRI investigation revealed altered activity during language tasks in participants with epilepsy compared to controls. In epilepsy with focal seizures originating in the left hemisphere, we found increased bilateral activation of supporting areas, in the anterior mid-cingulate cortex and the anterior ventral insulae, indicating a compensational functional reorganization. In generalized epilepsy, the functional language network showed an imbalance, as this group expressed an inadequate suppression of activation in the anterior temporal lobe during semantic processing. Subtle language impairment can, even if it does not occur in everyday dialogue, be of importance and have consequences for the person affected. The negative consequences of language decline must be addressed in people with epilepsy of different etiology. Young adults with epilepsy are still substantially affected by the condition. The consequences are not only restricted to the seizures, but concern many aspects of life and there is a great need for new treatment options for this group in the future.

Abstract [en]

The appearance of new anti-epileptic drugs (AED) during the last decade has provided neurologists and their patients with a greater choice, but the proof for their superiority over traditional AEDs is sparse, especially their use in adolescence and Young adulthood. We studied a group Of Young adults (18-27 years) with epilepsy and compared their Situation in 2004 with those 5 years earlier.

Materials and methods: The participants (n = 97) answered questionnaires regarding seizure-frequency, AED, side-effects and quality-of-life. Information was also taken from medical records.

Results: The use of new generation AEDs increased during the 5-year study period, particularly among women. However seizure frequency had not changed significantly over time, and compared to men the effectiveness in controlling seizures Was lower in women. The participants reported normal quality-of-life (QOL), which may indicate that the increase in number of AEDs to choose from actually improved the situation for these Young adults with epilepsy. Frequency of seizures and cognitive side-effects of AEDs were associated with a lower QOL.

Conclusions: More women than men seem to be treated with new AEDs, and that the increase in use of new AEDs does not reduce seizure frequency in young adulthood. The effectiveness in controlling seizures seems to be lower in women in the age group Studied. Further Studies are required to better understand how epilepsy related factors interact.

Abstract [en]

Objective: It is not clear how the psychosocial well-being of young people with epilepsy is affected by growing up with the condition. We studied self-esteem and sense of coherence in a group of young adults with epilepsy and compared the results with those obtained 5 years earlier. Methods: The participants (n = 97) answered questionnaires regarding self-esteem, sense of coherence, and medical characteristics. Results: Self-esteem and sense of coherence both decreased during the 5-year study period. Self-esteem was correlated to epilepsy-related variables. Participants who were seizure free scored higher on sense of coherence, but there was no association between seizure frequency and sense of coherence among participants who still experienced seizures. Conclusion: We found that there was a decline in both sense of coherence and self-esteem over time for young adults with epilepsy. Growing up with epilepsy can lead to impairment of sense of coherence. Sense of coherence does not significantly correlate with epilepsy-related factors, but mirrors the phenomenon of epilepsy. Self-esteem is associated with such epilepsy-related factors as seizure frequency.

Abstract [en]

Objective: Epilepsy can sometimes be followed by memory impairment. This can result from the underlying cause of epilepsy or from recurrent seizures, or can be a side effect of antiepileptic drugs or a symptom of another disease such as depression. The aim of the study described here was to explore the experience of living with epilepsy and subjective cognitive decline. less thanbrgreater than less thanbrgreater thanMethod: To better understand the deeper meaning of the phenomenon, a qualitative design was chosen. Fourteen adults aged 18-35 took part in focus group interviews. The participants were divided into four groups, two groups of women and two groups of men, and the interviews were conducted according to a semistructured protocol.

In contrast to seizures, the cognitive decline is persistent. The themes reflected different hardships faced by the participants. The consequences of living with epilepsy and cognitive impairment concerned education, employment, social life, self-esteem, and hope for the future. The participants were already using strategies to cope with their cognitive decline, but may benefit from help in developing new strategies to better adjust to their memory problems. Development of more educational programs for both people with epilepsy and their relatives could improve their difficult situations. With help, people can learn to adjust their goals in life and live a fulfilling life despite the disease.

Abstract [en]

People with epilepsy often display cognitive decline. Language function in epilepsy has been most thoroughly studied in temporal lobe epilepsy, but the impact of language deficits in epilepsy is not fully understood. The aim of this study was to evaluate the effect of epilepsy on language function with functional magnetic resonance imaging of brain activation, with behavioral methods and to relate language performance to demographic data, self-esteem and Quality of life. We specifically aimed to investigate if variation in epilepsy origin would relate to differences in language performance and if these differences could be associated with specific language activation patterns in the brain. We recruited people with epilepsy (29 in total), with focal onset seizures in either the left or right hemispheres or with generalized epilepsy; and 27 matching healthy controls. The participants’ language skills were measured with a phonemic word fluency test and a broader test measuring higher language functions. Functional magnetic resonance images of the brain were obtained during a word fluency and a sentence reading paradigm. Questionnaires on self-esteem and quality of life were collected. People with epilepsy of both focal and generalized origin had impaired function in semantic and verbal fluency tasks compared to the controls. The causes of language impairment were multifactorial; the most important determinants were education and onset age of epilepsy. Impaired language function was correlated to low self-esteem for participants with focal onset seizures; however Quality of life did not seem to be affected by language impairment. The functional magnetic resonance imaging investigation demonstrated altered functional activity during language tasks for participants with epilepsy compared to healthy controls. In epilepsy with focal seizures originating in the left hemisphere we found increased bilateral  activation of supporting areas in the anterior mid-cingulate cortex and the left anterior ventral insula, indicating a compensational functional reorganization. In generalized epilepsy, the functional language network showed an imbalance expressed as an inadequate  suppression of activation in the left anterior temporal lobe during semantic processing. Our study shows not only that reduced language functioning is present in people with epilepsy other than in the temporal lobe, but also that frequency of convulsive seizures correlates to language impairment. For patients with focalized seizures, low self esteem correlated also to language impairment. Our results highlight the importance of addressing the negative consequences of language decline in people with epilepsy of both focal and generalized origin.
