Anomia remains one of the most recalcitrant linguistic disruptions in aphasia to treat. Developing successful interventions to address the word-finding deficits are complicated by the post-stroke symptom variability and inconsistent recovery patterns associated with anomia. Most of the current treatment methods, with a focus on specific compensating techniques and the repetitive practice of a limited set of items, have had variable success in naming treatment. However, it has not been possible to predict the gains in generalizing the learning beyond the stimuli used in practice or the controlled clinical setting. In this preliminary case study, we explore the value of a novel treatment concept, grounded in centuries of cognitive-perceptual exercises in mindfulness training. It incorporates the practice of mental imagery and focused attention to remedy the broken phonological assembly patterns found in word finding deficits. The aim of this study was to evaluate the potential effectiveness of practicing the repeated activation of mental imagery of concrete objects as a therapeutic tool for repairing disorders of lexical retrieval in a subject with chronic moderate to severe word-finding deficits. This trial treatment was used to assist a right-handed, 68-year old educated male with a two-and-a-half years post-onset chronic severe aphasia (anomic type) secondary to a left hemispheric infarct. Two five-week long training protocols involving common (typical) and uncommon (less typical) categories of pictured objects were used for treating anomia. The first trial involved the blocked presentation of stimuli; the second trial, undertaken a year after, included a random presentation of stimuli. It was found that the impact was manifested in three ways: (1) an improved verbal naming of the treated objects; (2) retention of therapeutic gains by a successful generalization to untreated similar lexical items; and (3) importantly, serendipitous gains in the ability to concurrently write the names of the pictured objects. The post-treatment data on all blocked lexical trials, and some random lexical trials, were found to be significant on the Fisher’s exact test. The use of the visual mental imagery-based therapy had a positive impact on the partial restoration of the subject’s naming.

The aim of the study was to evaluate the quality of life of a patient af- terendarterectomy (CEA) of the Internal Carotid Artery (ICA) following an Acute ischemic stroke (AIS) during COVID-19. A right-handed, 51-year-old patient, a visual artist, single, in good health and no chronic illnesses to date, became infected with SARS-CoV-2 and contracted COVID-19. The presence of SARS-CoV-2 virus was confirmed by a RT PCR antigen test. The patient was hospitalized, and required mechanical ventilation at an Intensive Care Unit (ICU) before an acute ischemic stroke (AIS) onset. Except for untreated hypertension, her medical history was unremarkable. Her blood pressure was 180/100 mm Hg; her pulse was 76 beats per minute and was regular. AIS from the left middle cerebral artery (MCA) has resulted primarily in damage to the left hemisphere, and secondary effects on the right side resulting in body weakness and mild anomic aphasia. Magnetic resonance imaging (MRI) confirmed stroke and detected brain tissue damaged by an AIS. It revealed hyperintense foci in the T2 and FLAIR sequences, 21 mm in size in the left hemisphere of the brain. In search of the cause of AIS, CT angiography was performed. It revealed a large (90%) ICA occlusion. The patient was admitted to the emergency room at the Vascular Surgery Clinic with an Endovascular Subunit. The revascularization procedure (CEA) was performed under general endotracheal anesthesia with the use of the protocol and techniques (elaborated at the Department of Vascular Surgery and Endovascular Procedures, The John Paul II Hospital in Krakow). The CEA procedure improved her general health: she regained the ability to name objects and her HRQOL also improved in her perception. The improvement achieved was statistically significant. She returned to painting and functions well in society. The patient’s perception of HRQoL measured by the SF-36 domains was better after the CEA: a significant improvement in self-reported overall health has occured. The HRQoL outcome measures may be valuable in future clinical trials of comparing different methods of treatment offered after AIS.
