Parental rearing and intimate relations in women's depression.
Bowlby has suggested that attachment behavior is not restricted to early childhood but can remain valid through the life span. This study was designed to test whether recall of parental rearing (Parental Bonding Instrument) and perception of marital relationship (Dyadic Adjustment Scale) is significantly different between 2 groups of women: one with non-bipolar depressive disorder (DSM-III-R) compared with another (control) of healthy women from a primary practice setting. We also examined the hypothesis that exposure to dysfunctional parenting is associated with negative intimate relationships in adulthood. Our results partially support these hypotheses. We discuss the significance of these findings in the prevention and treatment of depressive disorders.

Alzheimer's disease, beta-amyloidosis, and aging.
Alzheimer's disease (AD) is rapidly moving from the obscure category of degenerative diseases to the more precise one of metabolic disorders. Recent discoveries have substantiated the hypothesis that AD results from the deposition of beta-amyloid, which is formed by polymers of a proteolytic fragment of the amyloid protein precursor (APP), and may induce intraneuronal aggregation of the microtubule-associated protein tau into paired helical filaments and neuronal death. There is also evidence that AD is a heterogeneous age-related disorder of multifactorial origin, which may arise as a consequence of point mutations of genes encoding APP or other proteins involved in its metabolism (familial AD), or a combination of genetic and non-genetic factors (sporadic AD). Familial AD displays genetic and phenotypic heterogeneity, meaning that mutations of different genes may cause the AD phenotype, and that different mutations of the same gene may cause phenotypically distinct disorders, including Alzheimer-type dementia and cerebral amyloid angiopathy with cerebral hemorrhages and stroke. On the other hand, aging, gender, head trauma, and variants of the apolipoprotein E gene have been shown to increase the risk of developing the more prevalent sporadic form of AD. The mechanisms by which these factors influence amyloidogenesis are beginning to be understood, and this will provide a rational basis for future therapy. Knowledge of the molecular basis of AD would eventually allow accurate risk prediction before the disease becomes clinically apparent, and better chances for early treatment and prevention.

[Psychiatric disorders and cognitive deterioration in Friedreich ataxia].
The present study was designed with the aim of examining the presence of psychiatric diagnosis and intellectual impairment in a sample of patients with Friedreich's ataxia. A consecutive sample of 21 patients presenting with Friedreich's Ataxia were evaluated by means of a neuropsychiatric interview. Only one patient was diagnosed as mentally retarded. Out of the 15 patients of the sample who were evaluated with be WAIS, all of them fell within a normal intellectual range. The idea that Friedreich's Ataxia produces cognitive impairment and serious psychiatric symptoms came from the earliest descriptions of the disease at the beginning of this century, which probably included many patients in their samples who had other diseases.
