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.
