Prevalence of mental disorders, personality traits and mental complaints in the Lundby Study. A point prevalence study of the 1957 Lundby cohort of 2,612 inhabitants of a geographically defined area who were re-examined in 1972 regardless of domicile.

The Lundby Study is a prospective, psychiatric-epidemiological study of a normal population that has been repeatedly examined over a period of 25 years. Experienced psychiatrists made home visits and collected the basic information through personal examinations adding supplementary data from other relevant sources. The present book contains point prevalence data of mental disorders such as neuroses, psychoses, organic brain syndromes, psychosomatic disorders, psychopathy, mental retardation, alcoholism, mental complaints, and also of various personality traits in a normal population at two points of time, 15 years apart. Together with earlier published incidence studies the present monograph is intended to give as complete a picture as possible of the mental morbidity in a total population. Our most conspicuous finding was the increase over time of the prevalence of neurotic illnesses. Depressive illnesses represented the largest increase. In the male sex the rate of Neurosis trebled from Time 1 to Time 2, although the female preponderance still remained. Psychopathy and Alcoholism, on the other hand, were very markedly male disorders. A description of how the investigations were performed is included and also a list of publications originating from the Lundby Study. This book will be of interest to physicians and psychiatrists interested in epidemiology and also to governmental planners and social scientists.

Mental tiredness in the Lundby study: incidence and course over 25 years.

The Lundby study is a prospective, epidemiological survey of mental health in a total population. When evaluating the material of 2550 individuals followed from 1947 to 1972, we found a large group with mental tiredness as the dominating symptom. Next to depression this was the most frequent diagnosis in the population. According to our concept of Tiredness, one third of the women ran a lifetime risk of developing a first-ever episode of Tiredness, while the risk for men was one fifth. The incidence of Tiredness is described together with the total frequency of episodes. The course of mental illness starting with a first episode of Tiredness within the 25-year investigation period shows that about one third of the men and half of the women relapsed into Tiredness or other mental illnesses, not infrequently with a serious outcome. However, most of the episodes of Tiredness lasted less than 2 years and were of milder impairment. We emphasize the importance of further investigations by means of epidemiological, clinical and neurochemical methods as regards the heterogeneous syndrome of mental fatigue.

Incidence of dementia in the Lundby Study.

The incidences of senile dementia of Alzheimer type (SDAT) and multi-infarction dementia (MID) were studied in a total Swedish population, the Lundby project. The study is prospective and covers a 25-year period. The incidence rates per year of contracting SDAT or MID and the probability in each 10-year age interval of contracting dementia in the elderly were calculated, as well as the cumulative risk up to a certain age. The lifetime risk of contracting SDAT was for men 25.5% and for women 31.9%. The corresponding figures for MID were 29.8 and 25.1%.

Vascular dementia in the Lundby study. 1. A prospective, epidemiological study of incidence and risk from 1957 to 1972.

In this study, a total population, the 1957 Lundby cohort, was investigated with regard to the incidence of vascular dementia over a 15-year period, and to provide a succeeding study with basic data concerning the background factors for vascular dementia. The 1957 cohort comprises 2,612 persons who were registered in the geographically delimited Lundby area on July 1, 1957. The lifetime risk of developing vascular dementia was found to be 34.5% in men and 19.4% in women when all degrees of impairment were taken into account, the preponderance for the male sex being very obvious.

Senile dementia of the Alzheimer type in the Lundby Study. I. A prospective, epidemiological study of incidence and risk during the 15 years 1957-1972.

In spite of the great impact of senile dementia of the Alzheimer type (SDAT) on society, far too little is known about its epidemiology. In this study of a total, normal population from a geographically delimited area in Sweden, Lundby, 2612 persons were examined in 1957 by one psychiatrist (Hagnell). In 1972 the same population was reexamined irrespective of domicile. The incidence and risk of contracting SDAT during the 15 years were calculated. No cases of SDAT were diagnosed before the age of 60 years. The lifetime risk was for men 25.7% and for women 26.2%. When only the very severely impaired were taken into account, the figures were 14.5% in men and 14.6% in women.

A prospective study of first-incidence depression. The Lundby study, 1957-72.

The present study is based on the so-called 1957 Lundby cohort, a geographically defined normal Swedish population of 2612 individuals who were evaluated for mental disorders in 1957 and 1972. The annual age-standardised first incidence of depression, with or without other psychiatric symptoms, all degrees of impairment included, was found to be 4.3 per 1000 person years in men and 7.6 per 1000 person years in women. Up until 70 years of age, the cumulative probability of suffering a first episode of depression was 27% in men and 45% in women.

Incidence of anxiety in the Lundby Study: changes over time during a quarter of a century.

2,550 persons from a geographically delimited area in Sweden were examined and described by a team of 4 psychiatrists in 1947. Mental disorders, personality traits, social factors etc. were recorded for all but 1% of the population. Irrespective of domicile the same persons were examined in the same way first 10, then another 15 years later. The incidence of 'Anxiety' up to 60 years of age was 9.9% in men and 19.7% in women. The majority of both sexes had their first episode as young adults or in the younger middle age (30-39 years). Among men with a 'severe and medium' impairment, the cumulative probability of disease was higher in the 15-year period 1957-1972 than in the 10-year period 1947-1957.

Current trends in the incidence of senile and multi-infarct dementia. A prospective study of a total population followed over 25 years; the Lundby Study.

Organic brain syndromes among the elderly have been studied prospectively in a total population during the 25-year period 1947-1972. The population (2,550 persons) originates from a geographically delimited area in southern Sweden (Lundby). The original population has been followed for 25 years irrespective of domicile. A comparison of incidences for the first 10-year period (1947-1957) and the second 15-year period (1957-1972) shows a decrease in organic brain syndromes in the population concerning multi-infarct as well as senile dementias.

Are we entering an age of melancholy? Depressive illnesses in a prospective epidemiological study over 25 years: the Lundby Study, Sweden.

The Lundby cohort consists of all inhabitants in a delimited area in Sweden studied in 1947 by Essen-Möller, then by Hagnell in 1957, and by Hagnell & Ojesjö in 1975. It has been claimed that depressive disorders have increased during the sixties and seventies. In order to examine this hypothesis on a normal population (the Lundby Study), comparisons were made of the incidence figures for depression during the periods 1947-57 and 1957-72, and during the five 5-year intervals within the period.

Incidence of alcoholism among men in the Lundby community cohort Sweden, 1957-1972. Probabilistic baseline calculations.

The annual age-standardized incidence rate of alcohol dependence among men in the Lundby community cohort prospectively observed during 1957-1972 (N = 2550) was 130 per 100,000 (including "alcohol abuse," 300 per 100,000). The individual expectancy of developing alcohol dependence in a lifetime was 8.6% (including "alcohol abuse," 19.3%). Of the cumulative probability, 78% was manifested by those under 40 years of age.
