A Pilot Study Examining Feasibility and Initial Efficacy of Remotely Delivered Cognitive Adaptation Training.

Cognitive Adaptation Training (CAT) is an evidence-based treatment that uses environmental supports including signs, text messages, checklists, smart pill containers, and the organization of belongings to bypass cognitive and motivational impairments and to cue adaptive behavior in the home or work environment. We developed and tested a remote version of CAT to make the treatment available more broadly. Because CAT is focused on working with the individual in their home environment to establish supports, CAT may not be as easy to translate into an effective virtual treatment as talk-therapies.

The Acceptability of Remotely Delivered Cognitive Adaptation Training.

Cognitive Adaptation Training (CAT) is a psychosocial treatment using environmental supports such as signs, checklists, technology, and the organization of belongings to bypass cognitive and motivational impairments for those with serious behavioral health problems. We conducted a survey of 204 members of managed Medicaid in Texas to examine the acceptability of, opinions about and preferences for CAT delivered in-person (CAT) or remotely (R-CAT) where supplies would be mailed and visits would occur via videoconferencing. The telephone survey presented descriptions of CAT and R-CAT in counterbalanced order eliciting general opinions about the treatments, such as (1) whether they would accept the treatments if they were offered the day of the survey at no cost, (2) which treatment was preferred, and (3) the extent to which they agreed or disagreed with a number of statements about components of the treatments.

PKMζ differentially utilized between sexes for remote long-term spatial memory.

It is well established that male rats have an advantage in acquiring place-learning strategies, allowing them to learn spatial tasks more readily than female rats. However many of these differences have been examined solely during acquisition or in 24h memory retention. Here, we investigated whether sex differences exist in remote long-term memory, lasting 30d after training, and whether there are differences in the expression pattern of molecular markers associated with long-term memory maintenance.

Acute physiological stress promotes clustering of synaptic markers and alters spine morphology in the hippocampus.

GluA2-containing AMPA receptors and their association with protein kinase M zeta (PKMζ) and post-synaptic density-95 (PSD-95) are important for learning, memory and synaptic plasticity processes. Here we investigated these synaptic markers in the context of an acute 1h platform stress, which can disrupt spatial memory retrieval for a short-term memory on the object placement task and long-term memory retrieval on a well-learned radial arm maze task. Acute stress increased serum corticosterone and elevated the expression of synaptic PKMζ while decreasing synaptic GluA2.

Robust training attenuates TBI-induced deficits in reference and working memory on the radial 8-arm maze.

Globally, it is estimated that nearly 10 million people sustain severe brain injuries leading to hospitalization and/or death every year. Amongst survivors, traumatic brain injury (TBI) results in a wide variety of physical, emotional and cognitive deficits. The most common cognitive deficit associated with TBI is memory loss, involving impairments in spatial reference and working memory.
