Elements of cognitive rehabilitation after right hemisphere stroke.

There are two basic approaches to cognitive training: (1) impairment training and (2) task specific training. Impairment training addresses impairments common to a number of tasks and attempts to offer a general benefit to all of the tasks at once. Task specific training focuses on the impairments that arise in a single task and attempts to improve performance on that task. Impairment training of spatial disorders following right hemisphere stroke has shown some success when curricula are properly designed. The success, however, is quite limited because of normal cognitive constraints and those occurring after brain damage. Task specific training in conjunction with the combined application of various cognitive principles appears more promising, but as yet, only a few studies exist. The neurologic factors are likely to be the same factors that influence recovery. The factors that influence trainability are lesion topography (size and location of the focus plus premorbid atrophy), lesion chronicity, and the presence of additional cognitive impairments (anosognosia, confusion, and abulia). Other interventions that may be beneficial, even for training resistant patients, include behavior modification, cognitive prostheses, and drugs.

Training the elderly on the ability factors of spatial orientation and inductive reasoning.

We examined the effects of cognitive training with elderly participants from the Seattle Longitudinal Study. Subjects were classified as having remained stable or having declined over the previous 14-year interval on each of two primary abilities, spatial orientation and inductive reasoning. Subjects who had declined on one of these abilities received training on that ability; subjects who had declined on both abilities or who had remained stable on both were randomly assigned to the spatial orientation or inductive reasoning training programs. Training outcomes were examined within an ability-measurement framework with empirically determined factorial structure. Significant training effects, at the level of the latent ability constructs, occurred for both spatial orientation and inductive reasoning. These effects were general, in that no significant interactions with decline status or gender were found. Thus, training interventions were effective both in remediating cognitive decline on the target abilities and in improving the performance of stable subjects.

Reserve capacity of the elderly in aging-sensitive tests of fluid intelligence: replication and extension.

Fluid intelligence belongs to that cluster of intellectual abilities evincing aging loss. To examine further the range of intellectual reserve available to aging individuals and the question of replicability in a new cultural and laboratory setting, 204 healthy older adults (mean age = 72 years; range = 60-86) participated in a short-term longitudinal training study. For experimental subjects, 10 sessions consisted of cognitive training involving two subability tests (Figural Relations, Induction) of fluid intelligence. The pattern of outcomes replicates and expands on earlier studies. Older adults have the reserve to evince substantial increases in levels of performance in fluid intelligence tests. Transfer of training, however, is narrow in scope. Training also increases accuracy of performance and the ability to solve more difficult test items. Difficulty level was estimated in a separate study, with a comparable sample of N = 112 elderly adults. Future research is suggested to examine whether intellectual reserve extends to near-maximum levels of performance.

"Theory of mind" in schizophrenia: a review of the literature.

The term theory of mind (ToM) refers to the capacity to infer one's own and other persons' mental states. A substantial body of research has highlighted the evolution of ToM in nonhuman primates, its emergence during human ontogeny, and impaired ToM in a variety of neuropsychiatric disorders, including schizophrenia. There is good empirical evidence that ToM is specifically impaired in schizophrenia and that many psychotic symptoms-for instance, delusions of alien control and persecution, the presence of thought and language disorganization, and other behavioral symptoms-may best be understood in light of a disturbed capacity in patients to relate their own intentions to executing behavior, and to monitor others' intentions. However, it is still under debate how an impaired ToM in schizophrenia is associated with other aspects of cognition, how the impairment fluctuates with acuity or chronicity of the schizophrenic disorder, and how this affects the patients' use of language and social behavior. In addition to these potential research areas, future studies may also address whether patients could benefit from cognitive training in this domain.

Cognitive rehabilitation in Parkinson's disease.

A rehabilitation program of 6 weeks, including both motor and cognitive training, was applied to 20 patients affected by Parkinson's disease (PD) in the early stages, presenting with mild cognitive deficits, but no dementia. Cognitive rehabilitation has been performed by utilizing a software elaborated for neuropsychological training (TNP). At the end of the scheduled sessions, the patients showed a significant improvement at verbal fluency, logic memory and Raven's matrices tests, as compared to baseline. These results remained stable over the time. We hypothesize that rehabilitative training exerts its positive effects by reinforcing cognitive strategies, in particular, by enhancing frontal function, which are typically impaired in PD, and suggests that this instrument could be implemented in nonpharmacological treatment of this pathology.

Outcomes of a computer-based cognitive rehabilitation program on Alzheimer's disease patients compared with those on patients affected by mild cognitive impairment.

The aim of the present study is to evaluate the outcomes of a computer-based cognitive training on patients affected by Alzheimer's disease (AD) compared with the outcomes on patients affected by mild cognitive impairment (MCI), multiple system atrophy (MSA). Ten AD patients aged 74.1+/-5.6 years, with mini-mental state examination (MMSE) score at baseline of 23.9+/-2.4, and 10 MCI patients aged 70.6+/-6.0 years, with MMSE score of 28.0+/-1.4, attending our day-hospital of neurorehabilitation were selected for the study. Three MSA patients aged 69.0+/-9.5 years, MMSE scores 26.7+/-2.3 were selected from the same setting in order to have a different control group. Each patient attended two training programs and was evaluated according to cognitive and non-cognitive functions at baseline at the end of the second training program. The AD group showed a significant MMSE score improvement (p=0.010). On the contrary, MMSE scores at baseline and at follow-up remained quite stable in the other two groups. AD patients also showed significant improvement in the areas of verbal production (p=0.036) and executive functions (p=0.050). MCI patients significantly improved in behavioral memory (p=0.017; p=0.011). No significant improvement was observed in MSA group. Our data seem to indicate that the same individualized rehabilitative intervention could have different effects according to patient's diagnosis. MCI and AD patients had significant improvements in global cognitive status and/or in specific cognitive areas. On the contrary, MSA patients did not benefit at all.

Stress management training for hypertensives: cognitive and physiological effects.

The contribution of training procedures designed to alter individuals' psychological responses to stressful life stimuli to the reduction of blood-pressure levels of hypertensives was evaluated. The treatment consisted of a set of coping skill-building experiences. Forty-one black males, mildly to moderately hypertensive and under medical supervision in an outpatient cardiovascular unit of a veterans' hospital, participated. Subjects were randomly assigned to one of three groups: Cognitive Self-Management Training (CSM), Attention Placebo Control, and Current Clinic Conditions Control. The dependent measures were the State Anxiety Scale, Trait Anxiety Scale, Coping Strategic Inventory, systolic blood pressure, and diastolic blood pressure. Subjects in the CSM group reported significant increases in the use of cognitive coping strategies in their lives and demonstrated significant decreases in measured levels of state anxiety and systolic blood pressure. Promising reductions of diastolic blood pressure ratings were obtained as well.

[New therapeutic activity in geriatric psychiatry].

The author mentions and describes in detail three dynamically oriented psychiatric activities which proved useful and became thus an important component of comprehensive treatment of demented patients. Part of the activating programme for patients with advanced affections of memory, orientation and concentrating capacity is Training in orientation and reality (TOR). Relaxation training (TR) helps patients to get rid of the sensation of tension, fear and uncertainty. Cognitive training (KT) helps to restore and improve cognitive functions. By means of the mentioned activities the authors reinforce persisting abilities and skills. In the conclusion the authors present recommendations which make the reader familiar with suitable communication with and treatment of clients suffering from organic brain affections.

Efficacy of psychological therapy in schizophrenia: conclusions from meta-analyses.

Over the past years, evidence for the efficacy of psychological therapies in schizophrenia has been summarized in a series of meta-analyses. The present contribution aims to provide a descriptive survey of the evidence for the efficacy of psychological therapies as derived from these meta-analyses and to supplement them by selected findings from an own recent meta-analysis. Relevant meta-analyses and randomized controlled trials were identified by searching several electronic databases and by hand searching of reference lists. In order to compare the findings of the existing meta-analyses, the reported effect sizes were extracted and transformed into a uniform effect size measure where possible. For the own meta-analysis, weighted mean effect size differences between comparison groups regarding various types of outcomes were estimated. Their significance was tested by confidence intervals, and heterogeneity tests were applied to examine the consistency of the effects. From the available meta-analyses, social skills training, cognitive remediation, psychoeducational coping-oriented interventions with families and relatives, as well as cognitive behavioral therapy of persistent positive symptoms emerge as effective adjuncts to pharmacotherapy. Social skills training consistently effectuates the acquisition of social skills, cognitive remediation leads to short-term improvements in cognitive functioning, family interventions decrease relapse and hospitalization rates, and cognitive behavioral therapy results in a reduction of positive symptoms. These benefits seem to be accompanied by slight improvements in social functioning. However, open questions remain as to the specific therapeutic ingredients, to the synergistic effects, to the indication, as well as to the generalizability of the findings to routine care.

[Neuropsychiatric and cognitive aspectos of multiple sclerosis].

Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease that can affect cognitive and emotional functioning. About 50% of MS patients present some degree of neuropsychological impairment. Due to its onset in young adulthood (a period of life in which the individual is professionally and socially very active) the presence of cognitive impairment may greatly alter the patient's daily living activities and future life plans. Memory, attention, executive function and information processing speed are the most commonly reported impaired aspects of cognition. Depression, euphoria, and pathological laughing and crying are frequent psychiatric findings. In this paper we describe the distinctive features of cognitive and psychopathological impairments and their relationship to certain disease variables such as illness duration, lesion sites, physical impairment and clinical course. We also deal with aspects of the neuropsychological and psychiatric assessment, emphasizing its importance when psychological counseling or an eventual cognitive training are needed.

Under-recruitment and nonselective recruitment: dissociable neural mechanisms associated with aging.

Frontal contributions to cognitive decline in aging were explored using functional MRI. Frontal regions active in younger adults during self-initiated (intentional) memory encoding were under-recruited in older adults. Older adults showed less activity in anterior-ventral regions associated with controlled use of semantic information. Under-recruitment was reversed by requiring semantic elaboration suggesting it stemmed from difficulty in spontaneous recruitment of available frontal resources. In addition, older adults recruited multiple frontal regions in a nonselective manner for both verbal and nonverbal materials. Lack of selectivity was not reversed during semantically directed encoding even when under-recruitment was diminished. These findings suggest two separate forms of age-associated change in frontal cortex: under-recruitment and nonselective recruitment. The former is reversible and potentially amenable to cognitive training; the latter may reflect a less malleable change associated with cognitive decline in advanced aging.

Methylphenidate and cognitive therapy: a comparison of treatment approaches with hyperactive boys.

This study of hyperactive boys evaluated the effects of three modes of treatment in relation to an untreated group. The treatments were administered over a 3-month period and included cognitive training, stimulant drug therapy (methylphenidate), and the two treatments combined. A follow-up assessment was conducted approximately 3 months after contact between the training staff and the child had ceased. Analyses of attentional deployment and cognitive style measures, tests of academic achievement, and behavioral ratings showed that only those children in the two medication treatment conditions demonstrated improvement in attentional deployment and behavioral ratings. In the cognitive therapy condition, there were changes only on measures of attentional deployment. The data did not provide evidence indicating that the combined medication and cognitive therapy condition was any more effective than that condition involving medication alone. Discussion provides future guidelines for evaluation of the relative effectiveness of stimulant drug therapy and other psychological treatment modalities.

Therapy-induced plasticity of cognitive functions in MS patients: insights from fMRI.

Multiple sclerosis (MS) is an inflammatory disease of the central nervous system whose pathological mechanisms are still not completely understood. Physical as well as cognitive deterioration are consequences within the disease process that have an extensive impact on the patient's quality of life. Therefore, understanding the functional background of spontaneous as well as induced remission is of high relevance. Studies on visualization of therapeutic effects of pharmacological or cognitive treatment by functional magnetic resonance imaging (fMRI) are still rare. From fMRI studies on focal brain lesions hypotheses on mechanisms of brain reorganization can be derived. This contribution will first give an overview of the existing studies using fMRI in MS, on cognitive decline, on cognitive treatment studies and its therapeutic effects on behavioural readouts in MS, and on therapy-induced brain plasticity and its possible visualization by fMRI. Results of a study on correlating the effects of cognitive training with changes in brain organization in patients with mild to severe cognitive impairment will be reported.

A self-training program in inductive reasoning for low-education elderly: tutor-guided training vs. self-training.

The main aim of this study was to compare the effectiveness of a self-training program in inductive reasoning run for elderly with low levels of education. Two different training settings were considered, i.e. tutor-guided training and self-training, to ascertain whether results obtained in both settings would be similar. A total of 25 subjects took part in this study (average age = 68.266, range = 60-85 years), all volunteers and residents of the city of Granada. A quasi-experimental design was used with random assignment to either training setting. The design was applied in four stages: pre-test, cognitive training (tutor-guided vs. self-trained inductive reasoning), post-test immediately after training and follow-up at 3 months. Results show considerable gains in inductive reasoning training both in tutor-guided and self-trained groups.

Improved function of hemiplegic upper extremity after cognitive sensory motor training therapy in chronic stroke patients: preliminary report of a case series.

BACKGROUND: Recovery of upper extremity functions after a severe stroke and traumatic brain injuries (TBI) have generally been less than satisfactory. The "cognitive sensory motor training therapy" is a relatively new method claimed to improve motor control using a specific type of repetitive sensory and motor re-learning protocol. There has been no previous study demonstrating the effectiveness of this method. OBJECTIVE: To investigate the value of the cognitive sensory motor training therapy to improve upper extremity motor function in chronic stroke and TBI patients. MATERIAL AND METHOD: Seven patients with persistent impaired upper extremity functions for over 6 months after a stroke or TBI were trained with the cognitive sensory motor training therapy program. Hand and arm functions were measured with Action Research Arm (ARA) test before the beginning of the study and once a month thereafter. Data were analyzed retrospectively. RESULTS: There was improvement of ARA scores in all of the trained patients. On average there was an increase of the ARA score of 7.7 points during the average training time of 2.5 months. CONCLUSION: The cognitive sensory motor training therapy may be an effective method for motor rehabilitation of chronic stroke or traumatic brain injured patients. Further prospective randomized control trials are justified and required.

Psychological skills training for sport-related outcomes: An umbrella review of evidence credibility and methodological quality.

Psychological skills training (PST) is widely used in sport, but review-level evidence remains fragmented across interventions, populations, outcomes, and methodological standards. This umbrella review synthesized evidence on PST-related interventions for sport-related outcomes, including athletic performance, psychological outcomes, cognitive performance, and sports injury, and evaluated evidence credibility, certainty, and methodological quality. A systematic literature search was conducted on 21 May 2025 in MEDLINE, PsycInfo, PubMed, Scopus, SportDiscus, Web of Science, and CINAHL Complete. Overall, 61 reviews involving 42,106 participants were included; 35 meta-analyses involving 28,076 participants were eligible for quantitative synthesis, and 26 reviews or meta-analyses involving 14,030 participants were summarized qualitatively. Quantitative findings showed generally positive point estimates for mindfulness-based interventions, imagery practice, music-based interventions, neurofeedback, perceptual-cognitive training, and multiple PST interventions, but most findings were weak or non-significant and certainty was generally very low. Qualitative evidence suggested potential benefits, but conclusions varied according to intervention definition, delivery, outcome measurement, and methodological quality. Evidence was more developed for athletic performance and psychological outcomes than for cognitive performance and sports injury. Overall, PST-related interventions may benefit sport-related outcomes, but conclusions should remain cautious because of low certainty, methodological heterogeneity, and limited evidence credibility.

Limbic tract anomalies in pediatric myelomeningocele and Chiari II malformation: anatomic correlations with memory and learning--initial investigation.

PURPOSE: To prospectively determine anomalies of limbic tracts and to describe the relationship between these anomalies, seen on diffusion-tensor magnetic resonance (MR) and fiber tract (FT) reconstruction images, and learning and memory in children with myelomeningocele (MM) and Chiari II malformation. MATERIALS AND METHODS: The investigation was HIPAA compliant and approved by institutional review boards; informed consent was obtained. In seven male and six female patients (aged 6 months to 16 years) with MM and Chiari II malformation, diffusion-tensor imaging and FT reconstruction were performed. FT reconstruction was generated with fractional anisotropy continuous tracking algorithm and manually drawn regions of interest. Limbic tract abnormalities were assessed on FT reconstruction images by an experienced pediatric neuroradiologist blinded to results of cognitive testing. Nine patients met criteria for memory and learning testing by a trained cognitive neuroscientist blinded to MR results. Exact Wilcoxon rank sum test was used to compare performance with learning and memory tasks in two groups. RESULTS: Eleven of 13 patients had defects within fornices and/or cingulum; three patients had aberrant fibers of cingulum. In nine patients, six had deficits in general memory; four, in learning; and four, in both. Atresia or hypoplasia of crura and body of fornices was noted in six patients with memory deficits and four patients with learning deficits. Five of six patients with memory deficits and three of four with learning deficits had hypoplasia or atresia of cingulum. Exact Wilcoxon rank sum test demonstrated significantly poorer performance for nonverbal immediate recall tasks in patients with anomalies of the fornix compared with those without (P = .04, exact two-tailed test). CONCLUSION: Diffusion-tensor and FT reconstruction images revealed that limbic fiber abnormalities were common in patients with MM and Chiari II malformation. Nonverbal immediate recall task performance appeared to be related to abnormalities of the fornix.

Retraining attention in MS.

Cognitive decline is frequently observed in multiple sclerosis (MS) and has a major impact on quality of life. Therefore it would be important to offer therapeutic strategies to the patients. In the past, several studies were conducted on pharmacological or cognitive treatment. However, there is currently no specific treatment for cognitive decline and the studies published so far report heterogeneous results. The present paper focuses on the cognitive treatment strategies by reviewing and discussing the few studies that have been carried out in this area. In addition, results of a recently completed fMRI study on the visualization of cognitive training effects will be reported. This review clearly points out that further research in this area is needed to clarify the effects of cognitive intervention. Larger sample sizes and standardized neuropsychological outcome measures as well as standardized training tools are required to allow for comparisons between different studies and to improve our understanding of cognitive decline and the processes of cognitive recovery in MS.
