Eron aika : Tyttärien kertomuksia ikääntyneen vanhemman kuolemasta

There is a relative absence of sociological and cultural research on how people deal with the death of a family member in the contemporary western societies. Research on this topic has been dominated by the experts of psychology, psychiatry and therapy, who mention the social context only in passing, if at all. This gives an impression that the white westerners bereavement experience is a purely psychological phenomenon, an inner journey, which follows a natural, universal path. Yet, as Tony Walter (1999) states, ignoring the influence of culture not only impoverishes the understanding of those work with bereaved people, but it also impoverishes sociology and cultural studies by excluding from their domain a key social phenomenon. This study explores the cultural dimension of grief through narratives told by fifteen of recently bereaved Finnish women. Focussing on one sex only, the study rests on the assumption of the gendered nature of bereavement experience. However, the aim of the study is not to pinpoint the gender differences in grief and mourning, but to shed light on women s ways of dealing with the loss of a loved one in a social context. Furthermore, the study focuses on a certain kind of loss: the death of an elderly parent. Due to the growth in the life expectancy rate, this has presumably become the most typical type of bereavement in contemporary, ageing societies. Most of population will face the death of a parent as they reach the middle years of the life course. The data of this study is gathered with interviews, in which the interviewees were invited to tell a narrative of their bereavement. Narrative constitutes a central concept in this study. It refers to a particular form of talk, which is organised around consequential events. But there are also other, deeper layers that have been added to this concept. Several scholars see narratives as the most important way in which we make sense of experience. Personal narratives provide rich material for mapping the interconnections between individual and culture. As a form of thought, narrative marries singular circumstances with shared expectations and understandings that are learned through participation in a specific culture (Garro & Mattingly 2000). This study attempts to capture the cultural dimension of narrative with the concept of script , which originates in cognitive science (Schank & Abelson 1977) and has recently been adopted to narratology (Herman 2002). Script refers to a data structure that informs how events usually unfold in certain situations. Scripts are used in interpreting events and representing them verbally to others. They are based on dominant forms of knowledge that vary according to time and place. The questions that were posed in this study are the following. What kind of experiences bereaved daughters narrate? What kind of cultural scripts they employ as they attempt to make sense of these experiences? How these scripts are used in their narratives? It became apparent that for the most of the daughters interviewed in this study the single most important part of the bereavement narrative was to form an account of how and why the parent died. They produced lengthy and detailed descriptions of the last stage of a parent s life in contrast with the rest of the interview. These stories took their start from a turn in the parent s physical condition, from which the dying process could in retrospect be seen to have started, and which often took place several years before the death. In addition, daughters also talked about their grief reactions and how they have adjusted to a life without the deceased parent. The ways in which the last stage of life was told reflect not only the characteristic features of late modernity but also processes of marginalisation and exclusion. Revivalist script and medical script, identified by Clive Seale as the dominant, competing models for dying well in the late modern societies, were not widely utilised in the narratives. They could only be applied in situations in which the parent had died from cancer and at somewhat younger age than the average. Death that took place in deep old age was told in a different way. The lack of positive models for narrating this kind of death was acknowledged in the study. This can be seen as a symptom of the societal devaluing of the deaths of older people and it affects also daughters accounts of their grief. Several daughters told about situations in which their loss, although subjectively experienced, was nonetheless denied by other people.

Dementiakuolleisuuden sosiaaliset determinantit - rekisteriaineistoon pohjautuva tutkimus dementiakuolleisuuteen vaikuttavista sosiodemografisista tekijöistä

Tutkimuksessa tarkastellaan dementiakuolleisuutta sekä siihen vaikuttavia sosiaalisia tekijöitä. Dementia on oireyhtymä, jota pääasiassa sairastavat yli 65 -vuotiaat henkilöt. Väestön ikääntyessä sekä elinajanodotteen kasvaessa on odotettavissa, että dementiaa sairastavien määrä tulee kasvamaan merkittävästi lähivuosina. On viitteitä siitä, että dementiaan sairastumisen riskiin vaikuttavat erilaiset sosiaaliset tekijät kuten koulutus, mutta varsinkin dementiakuolleisuudesta tiedetään vähän. Tutkielman aineistona käytettiin Tilastokeskuksen muodostamaa Elinolot ja kuolinsyyt -rekisteriaineistoa, joka koostuu väestölaskentatiedoista sekä työssäkäyntitilaston pitkittäisaineistosta, johon on liitetty kuolinsyytietoja. Peruskuolinsyyn lisäksi aineistossa oli tieto korkeintaan kolmesta myötävaikuttavasta syystä. Dementiakuolleisuuden on esitetty aliarvioituvan peruskuolinsyynä, joten dementiakuolleisuuden määrittelyssä käytettiin myös tietoa myötävaikuttavista syistä. Rajausten jälkeen aineistossa on 317 944 henkilöä, joista 128 562 on miehiä ja 189 382 naisia. Pääanalyysimenetelmänä on käytetty elinaikamalleihin kuuluvaa Coxin regressiota. Dementiakuolleisuudessa oli vaihtelua kaikkien tutkimuksessa käytettyjen muuttujien, eli koulutuksen, sosiaaliluokan, tulojen, siviilisäädyn sekä perhemuodon mukaan. Koulutuksen vaikutus välittyi osin ammattiasemaan perustuvan sosiaaliluokan kautta. Suurimpia ryhmien väliset suhteelliset erot olivat nuoremmissa ikäryhmissä sekä sosiaaliluokan ja siviilisäädyn kohdalla. Eronneilla ja naimattomilla oli selvästi kohonnut riski suhteessa naimisissa oleviin. Myös työntekijöillä havaittiin kohonnut riski suhteessa ylempiin toimihenkilöihin. Siviilisääty vaikutti olevan merkittävä tekijä siinä mielessä, että koulutuksen, sosiaaliluokan ja tulojen tuominen malliin ei juuri vaikuttanut siviilisäätyryhmien välillä havaittuun vaihteluun. Dementiakuolleisuudessa havaitut ryhmien väliset suhteelliset erot olivat hieman pienempiä kuin muissa syissä, mutta kuitenkin hyvin samaa suuruusluokkaa. Tulosten perusteella on identifioitavissa tekijöitä, jotka suojaavat dementialta. Erityisesti avioliitto, korkea koulutus sekä ylemmät toimihenkilöammatit vaikuttavat olevan dementialta suojaavia tekijöitä. Avioliiton suojaavan vaikutuksen voidaan tulkita liittyvän sosiaaliseen kanssakäymiseen sekä puolison tukeen ja läsnäoloon. Korkea koulutus sekä toimihenkilöammatit indikoivat virikkeellisempää työympäristöä, mutta niiden vaikutus voi myös kulkea ylipäänsä aktiivisemman ja kognitiivisesti virikkeellisemmän elämäntavan kautta. Aktiivisen ja kognitiivisesti haastavan elämäntavan on esitetty suojaavan dementiaan sairastumiselta. Tuloksia voidaan tulkita elämänkaarinäkökulman kautta. Jo nuoruudessa vaikuttavilla tekijöillä, kuten koulutuksella, on vaikutusta. Tämän lisäksi elämänkaaren aikana myöhemmin vaikuttavat tekijät ovat merkityksellisiä. Näiden tekijöiden on esitetty vaikuttavan aivojen hermoverkostoon ja -yhteyksiin ja luovan kognitiivista reserviä, minkä on esitetty ehkäisevän tai lykkäävän dementiaan sairastumista.

Poststroke survival and ischemic stroke recurrence : the cerebral small-vessel disease perspective

The aim of the present study was to investigate the influence of different manifestations of cerebral SVD on poststroke survival and ischemic stroke recurrence in long-term follow-up. The core imaging features of small-vessel disease (SVD) are confluent and extensive white matter changes (WMC) and lacunar infarcts. These are associated with minor motor deficits but a major negative influence on cognition, mood, and functioning in daily life, resulting from small-vessel lesions in the fronto-subcortical brain network. These sub-studies were conducted as part of the Helsinki Stroke Aging Memory (SAM) study. The SAM cohort consisted of 486 consecutive patients aged 55 to 85 years who were admitted to Helsinki University Central Hospital with acute ischemic stroke. The study included comprehensive clinical, neuropsychological, psychiatric and radiological assessment three months poststroke. The patients were followed up up for 12 years using extensive national registers. The effect of different manifestations of cerebral SVD on poststroke survival and stroke recurrence was analyzed controlling for factors such as age, education, and cardiovascular risk factors. Poststroke dementia and cognitive impairment relate to poor long-term survival. In particular, deficits in executive functions as well as visuospatial and constructional abilities predict poor outcome. The predictive value of cognitive deficits is further underlined by the finding that depression-executive dysfunction syndrome (DES), but not depression in itself, is associated with poor poststroke survival. Delirium is not independently associated with increased risk for long-term poststroke mortality, although it is associated with poststroke dementia. Furthermore, acute index stroke attributable to SVD is associated with poorer long-term survival and a higher risk for cardiac death than other stroke subtypes. Severe WMC, a surrogate of SVD, is independently related to an increased risk of stroke recurrence at five years. In summary, cognitive poststroke outcomes reflecting changes in the executive network brain, and the presence of cerebral SVD are important determinants of poststroke mortality and ischemic stroke recurrence, regardless of whether SVD is the cause of the index stroke or a condition concurrent to some other etiology.

Dissection of the genetic background of childhood onset progressive myoclonic epilepsies

The progressive myoclonic epilepsies (PMEs) are a clinically and etiologically heterogeneous group of symptomatic epilepsies characterized by myoclonus, tonic-clonic seizures, psychomotor regression and ataxia. Different disorders have been classified as PMEs. Of these, the group of neuronal ceroid lipofuscinoses (NCLs) comprise an entity that has onset in childhood, being the most common cause of neurodegeneration in children. The primary aim of this thesis was to dissect the molecular genetic background of patients with childhood onset PME by studying candidate genes and attempting to identify novel PME-associated genes. Another specific aim was to study the primary protein properties of the most recently identified member of the NCL-causing proteins, MFSD8. To dissect the genetic background of a cohort of Turkish patients with childhood onset PME, a screen of the NCL-associated genes PPT1, TPP1, CLN3, CLN5, CLN6, MFSD8, CLN8 and CTSD was performed. Altogether 49 novel mutations were identified, which together with 56 mutations found by collaborators raised the total number of known NCL mutations to 364. Fourteen of the novel mutations affect the recently identified MFSD8 gene, which had originally been identified in a subset of mainly Turkish patients as the underlying cause of CLN7 disease. To investigate the distribution of MFSD8 defects, a total of 211 patients of different ethnic origins were evaluated for mutations in the gene. Altogether 45 patients from nine different countries were provided with a CLN7 molecular diagnosis, denoting the wide geographical occurrence of MFSD8 defects. The mutations are private with only one having been established by a founder-effect in the Roma population from the former Czechoslovakia. All mutations identified except one are associated with the typical clinical picture of variant late-infantile NCL. To address the trafficking properties of MFSD8, lysosomal targeting of the protein was confirmed in both neuronal and non-neuronal cells. The major determinant for this lysosomal sorting was identified to be an N-terminal dileucine based signal (9-EQEPLL-14), recognized by heterotetrameric AP-1 adaptor proteins, suggesting that MFSD8 takes the direct trafficking pathway en route to the lysosomes. Expression studies revealed the neurons as the primary cell-type and the hippocampus and cerebellar granular cell layer as the predominant regions in which MFSD8 is expressed. To identify novel genes associated with childhood onset PME, a single nucleotide polymorphism (SNP) genomewide scan was performed in three small families and 18 sporadic patients followed by homozygosity mapping to determine the candidate loci. One of the families and a sporadic patient were positive for mutations in PLA2G6, a gene that had previously been shown to cause infantile neuroaxonal dystrophy. Application of next-generation sequencing of candidate regions in the remaining two families led to identification of a homozygous missense mutation in USP19 for the first and TXNDC6 for the second family. Analysis of the 18 sporadic cases mapped the best candidate interval in a 1.5 Mb region on chromosome 7q21. Screening of the positional candidate KCTD7 revealed six mutations in seven unrelated families. All patients with mutations in KCTD7 were reported to have early onset PME, rapid disease progression leading to dementia and no pathologic hallmarks. The identification of KCTD7 mutations in nine patients and the clinical delineation of their phenotype establish KCTD7 as a gene for early onset PME. The findings presented in this thesis denote MFSD8 and KCTD7 as genes commonly associated with childhood onset symptomatic epilepsy. The disease-associated role of TXNDC6 awaits verification through identification of additional mutations in patients with similar phenotypes. Completion of the genetic spectrum underlying childhood onset PMEs and understanding of the gene products functions will comprise important steps towards understanding the underlying pathogenetic mechanisms, and will possibly shed light on the general processes of neurodegeneration and nervous system regulation, facilitating the diagnosis, classification and possibly treatment of the affected cases.
