Article Synopsis
  • Non-polyglutamine CACNA1A variants are linked to a diverse range of symptoms including developmental delay, migraines, epilepsy, psychiatric issues, and chronic cerebellar signs, with most patients showing symptoms from childhood.
  • In a study over 20 years, 41 patients were monitored, revealing that 66% required interval therapy, which effectively managed their episodic symptoms.
  • The findings suggest that non-polyglutamine CACNA1A disease presents differently as patients age, and that targeted prophylaxis can significantly alleviate their symptoms.

Both, decline of sensorimotor functions and cortical thickness are known processes in healthy aging. Physical activity has been suggested to enhance the execution of daily routine activities and to extend the time of functional independence in advanced age. We hypothesized that cortical thickness of motor areas in retired individuals could be related to physical demands of the profession carried out during working life.

To minimize recurrence following resection of a cerebral metastasis, whole-brain irradiation therapy (WBRT) has been established as the adjuvant standard of care. With prolonged overall survival in cancer patients, deleterious effects of WBRT gain relevance. Sector irradiation (SR) aims to spare uninvolved brain tissue by applying the irradiation to the resection cavity and the tumor bed.

Article Synopsis
  • Trust is essential in human society, and research has identified various biological factors, including brain areas, hormones, and genetics, that influence trust behavior, but the role of cortisol, particularly at basal levels, has been overlooked.
  • An experimental study compared trust behavior and plasma cortisol levels between patients with juvenile myoclonic epilepsy and healthy controls, revealing no significant difference in trust behavior but a trend towards lower trust in epilepsy patients and significant differences in cortisol levels.
  • The study found a correlation between cortisol levels and trust only in the epilepsy group, suggesting that future research should differentiate between acute and chronic stress effects on trust behavior.

Objective: To assess the role of cognitive reserve, age, gender and brain structure in proper name retrieval in advanced age.

Method: Performance in 2 naming tasks (asking for proper names or common names) and 2 memory tasks was assessed. In separate hierarchical regressions, we evaluated whether retrieval was predicted by gray matter thickness or volume in selected structures (Model 1) and whether the addition of age and gender (Model 2) or of education (Model 3) explained significantly more variance.

Background: Subarachnoid hemorrhage (SAH) is a devastating disease associated with high mortality and morbidity. Besides neurological sequelae, neuropsychological deficits largely contribute to patients' long-term quality of life. Little is known about the pituitary gland volume (PGV) after SAH compared to healthy referents and the association of PGV with long-term outcome including cognitive function.

Recent evidence has suggested that the hippocampus supports learning and retrieval of arithmetic facts during childhood and adolescence. Whether the hippocampus is also involved in retrieving overlearned arithmetic facts (such as 3 × 5 = 15) during adult age is open for investigation. In this study, we assessed whether patients with hippocampal atrophy due to Alzheimer's disease (AD) are still able to retrieve overlearned arithmetic facts from memory.

Studies indicate that a brief period of wakeful rest after learning supports memory retention, whereas distraction weakens it. It is open for investigation whether advanced age has a significant effect on the impact of post-learning wakeful rest on memory retention for verbal information when compared to a cognitively demanding distraction task. In this study, we examined (1) whether post-learning rest promotes verbal memory retention in younger and older adults and (2) whether the magnitude of the rest benefit changes with increasing age.

Background And Purpose: CACNA1A encodes the α1 subunit of the neuronal calcium channel P/Q. CACNA1A mutations underlie three allelic disorders: familial hemiplegic migraine type 1 (FHM1), episodic ataxia type 2 (EA2) and spinocerebellar ataxia type 6 (SCA6). A clear-cut genotype-phenotype correlation is often lacking since clinical manifestations may overlap.
