Older adults with subjective memory complaints benefit from memory strategy training, especially in their memory functioning in daily life. (JINS, 2018, 24, 1110-1120).

The beneficial effects of chronic and early pharmacological treatment with ethosuximide on epileptogenesis were studied in a genetic absence epilepsy model comorbid for depression. It was also investigated whether there is a critical treatment period and treatment length. Cortical excitability in the form of electrical evoked potentials, but also to cortico-thalamo-cortical network activity (spike–wave discharges, SWD and afterdischarges), white matter changes representing extra corticothalamic functions and depressive-like behavior were investigated. WAG/Rij rats received either ethosuximide for 2 months (post natal months 2–3 or 4–5), or ethosuximide for 4 months (2–5) in their drinking water, while control rats drank plain water. EEG measurements were made during treatment, and 6 days and 2 months post treatment. Behavioral test were also done 6 days post treatment. DTI was performed ex vivo post treatment. SWD were suppressed during treatment, and 6 days and 2 months post treatment in the 4 month treated group, as well as the duration of AD elicited by cortical electrical stimulation 6 days post treatment. Increased fractional anisotropy in corpus callosum and internal capsula on DTI was found, an increased P8 evoked potential amplitude and a decreased immobility in the forced swim test. Shorter treatments with ETX had no large effects on any parameter. Chronic ETX has widespread effects not only within but also outside the circuitry in which SWD are initiated and generated, including preventing epileptogenesis and reducing depressive-like symptoms. The treatment of patients before symptom onset might prevent many of the adverse consequences of chronic epilepsy.

Higher levels of CR seem to enable individuals to use effective strategies. These results highlight the importance of the role of CR in compensating for the aging-related memory decline.

BackgroundSubjective memory complaints (SMC) are common among older adults, but it is unclear to what extent adults with SMC spontaneously use memory strategies to compensate for their memory problems. As SMC may be a risk factor for memory decline later, it is important to extend our knowledge about spontaneous compensatory mechanisms in older adults with SMC.MethodSelf-reported strategy use and observed strategy use were assessed in 38 adults with and 38 without SMC.ResultsAdults with SMC used more strategies in daily life than those without. In the SMC group, memory complaints were positively correlated with strategy use. Only in adults without SMC, a significant correlation was found between observed strategy use and task performance.ConclusionStrategy use in older adults with SMC may be compensatory in nature, but did not increase their objective memory performance. Therefore, older adults with SMC might benefit from interventions aimed at optimizing strategy use.

The Modified Six Elements Test (MSET) assesses several executive functions. We examined whether an adapted scoring method is appropriate for discriminating between brain-injured persons with and without executive deficits. A MSET was administered to 70 participants with acquired brain injury in the chronic phase. The group was divided into individuals with and without executive impairments based on several other executive tests. The discriminative value for both the conventional raw score and the adapted scoring method was evaluated using receiver operating characteristic analyses. Both scoring methods discriminated significantly between persons with impaired and unimpaired executive functions (raw score: area under the curve, AUC = 0.703, p = .004; adapted score: AUC = 0.780, p = .000). Only the adapted scoring method proved sensitive (81%) and specific (67%) within a clinically useful range. Within this range, an acceptable cut-off score could be determined. Altogether, the proposed MSET scoring index is a potentially clinically useful contribution to the measurement of executive functions.
