    ABSTRACT Adult‐onset cerebral adrenoleukodystrophy is potentially treatable but often difficult to recognize before advanced cerebral involvement. Herein, we describe three men with early‐stage disease who initially presented with subtle visual complaints rather than subcortical dementia. Targeted neuropsychological testing revealed higher‐order visual dysfunction and posterior interhemispheric disconnection signs, including visual‐field‐dependent reading or naming deficits and dichotic listening abnormalities. Diffusion tensor imaging showed preferential involvement of posterior callosal and visual stream‐related white‐matter pathways. These findings define a posterior disconnection phenotype of adult‐onset cerebral adrenoleukodystrophy and provide a clinically useful framework for early recognition and timely therapeutic consideration of this treatable leukodystrophy.

    Abstract Altered eating behaviours are a hallmark of behavioural variant frontotemporal dementia (bvFTD) but are less well characterised in progressive nonfluent aphasia (PNFA) and semantic dementia (SD). We investigated the frequency and onset of eating behaviour changes across the three subtypes. We retrospectively reviewed the data of 58 patients (14 bvFTD, 30 PNFA and 14 SD). The presence and onset of eating changes were assessed using the Neuropsychiatric Inventory and medical records. Eating behaviours were categorised into overeating, reduced food intake and food preference change. Primary outcomes were prevalence and incidence rates from the initial disease symptoms. A time‐to‐event analysis was used to compare the cumulative incidence of eating behaviour changes; cumulative incidence curves were estimated using the Kaplan–Meier method; and group differences were assessed using the log‐rank test. Although the prevalence of eating changes was the highest in bvFTD (85.7%), followed by PNFA (63.3%) and SD (57.1%), the differences were not statistically significant ( p  = .220). Incidence also did not differ significantly ( p  = .054). However, overeating was significantly more frequent in the bvFTD group than in the PNFA and SD groups ( p  = .011). Changes in appetite and eating behaviour are common across the frontotemporal dementia spectrum and are not limited to bvFTD. Although the overall prevalence is similar across subtypes, overeating is specifically observed in bvFTD, whereas reduced food intake and food preference changes occur non‐specifically.

    OBJECTIVE The Wada test, an intracarotid amobarbital procedure, is the gold standard for preoperative evaluation of postoperative memory decline in patients with drug-resistant epilepsy. However, it has certain limitations including false negatives due to insufficient hippocampal inhibition and false positives due to extrahippocampal disorders such as aphasia. This study examined the utility of posterior cerebral artery (PCA) selective anesthesia for functional evaluation (SAFE) as an alternative approach to avoid aphasia and assessed its predictive value for postoperative verbal memory decline. METHODS The authors conducted a single-center retrospective study of patients with drug-resistant epilepsy between May 2018 and December 2023, who subsequently underwent PCA SAFE before anterior temporal lobe resection. The SAFE protocol includes comparable memory tasks before and immediately after anesthetic infusion. Preinfusion assessments established baseline memory function, whereas postinfusion assessments evaluated brain function under selective anesthesia. Patients were required to memorize 8 words, 8 pictures, and 5 figures. After the anesthetic effects subsided, recognition tasks were performed for all presented stimuli. The memory score was calculated by subtracting the number of recognized items encoded under anesthesia from the baseline. Word recognition represented verbal memory, whereas figure recognition represented visual memory. A memory score ≥ 2 points on the side of the epileptic focus or no difference between left and right PCA SAFE was classified as a high risk of postoperative memory decline. A decline of ≥ 15 points in postoperative memory scores on the Wechsler Memory Scale–Revised was defined as significant memory decline. RESULTS The authors included 11 patients (focus side: left in 8 patients and right in 3 patients). Five patients were classified as having a high risk and 6 as having a low risk for verbal memory decline. All 5 high-risk patients revealed significant postoperative verbal memory decline, whereas 5 of the 6 low-risk patients did not. The sensitivity was 83.3%, and the specificity was 100%. No patients had a significant decline in postoperative visual memory. CONCLUSIONS PCA SAFE was shown to predict postoperative verbal memory decline with high accuracy. This study highlights the utility of PCA SAFE in reducing aphasic interference in verbal memory, leading to a more accurate evaluation of surgical candidacy in patients with drug-resistant epilepsy.

    Abstract Alzheimer’s disease (AD)-related primary progressive aphasia (PPA) exhibits considerable heterogeneity in clinical presentation and neuroimaging patterns. No studies have quantitatively assessed cerebral perfusion patterns or systematically evaluated the internal heterogeneity of linguistic and neuroimaging features in this population. This study aimed to investigate cerebral hypoperfusion patterns and elucidate their correlation with diverse linguistic features in patients with AD-related PPA using a data-driven approach. Eleven patients with AD-related PPA and 34 with non-AD-related PPA were categorized based on cerebrospinal fluid biomarkers, and their single-photon emission computed tomography (SPECT) data were analyzed. Cerebral hypoperfusion was assessed across 56 regions of interest (ROIs) covering the entire cerebral hemisphere. Sparse principal component (sPC) analysis was performed on the AD-related PPA group to identify distinct patterns of cerebral perfusion reduction and correlate these components with clinical assessments of linguistic abilities. AD-derived sPCs were identified, reflecting hypoperfusion patterns in the left temporoparietal, frontal, and temporal pole regions, corresponding to regions typically associated with logopenic, nonfluent, and semantic variants. In both AD-PPA and non-AD-PPA, the sPC corresponding to the anterior temporal region was associated with semantic comprehension deficits, whereas that corresponding to the frontal region was linked to nonfluent speech and Kana writing impairment. sPC-based hierarchical clustering revealed clusters corresponding to logopenic, nonfluent, and semantic variants, with the anomic subtype distinguished from logopenic PPA. AD-positive cases were distributed across these clusters, emphasizing AD-PPA heterogeneity. These findings suggested that AD-related PPA heterogeneity is reflected in distinct cerebral perfusion patterns, which correlate with varying linguistic deficits.

    Hippocampectomy is effective for drug-resistant mesial temporal lobe epilepsy with hippocampal sclerosis. However, multiple studies have reported high risks associated with hippocampectomy in patients with mesial temporal lobe epilepsy without hippocampal sclerosis on magnetic resonance imaging and in those with preserved memory function. Verbal memory and language functions are believed to coexist in the same hemisphere. We present a case of left mesial temporal lobe epilepsy with atypical memory function lateralization revealed by super-selective infusion of propofol to the intracranial artery (super-selective Wada test). A 24-year-old right-handed man with drug-resistant focal impaired awareness seizures was diagnosed with left mesial temporal lobe epilepsy without hippocampal sclerosis, but he showed preserved verbal intelligence quotient and memory, suggesting a high risk of severe memory decline after hippocampectomy. We performed super-selective Wada test to the posterior cerebral artery to assess the lateralization of verbal and visual memory separately, and to the middle cerebral artery to assess language function. The results revealed right-sided dominance for both verbal and visual memory, although the language was left-dominant. Hippocampectomy was performed and resulted in freedom from seizures. Memory assessments 1 year postoperatively showed no decline in all subtests. In patients with drug-resistant epilepsy exhibiting atypical neuropsychological profiles, the memory-dominant, and language-dominant hemispheres may not align; detailed evaluations of function lateralization are necessary for tailored treatment.

    BACKGROUND: Disproportionately enlarged subarachnoid space hydrocephalus (DESH) is one of the neuroradiological characteristics of idiopathic normal pressure hydrocephalus (iNPH), which makes statistical analyses of brain images difficult. This study aimed to develop and validate methods of accurate brain segmentation and spatial normalisation in patients with DESH by using the Computational Anatomy Toolbox (CAT12). METHODS: Two hundred ninety-eight iNPH patients with DESH and 25 healthy controls (HCs) who underwent cranial MRI were enrolled in this study. We selected the structural images of 169 patients to create customised tissue probability maps and diffeomorphic anatomical registration through exponentiated Lie algebra (DARTEL) templates for patients with DESH (DESH-TPM and DESH-Template). The structural images of 38 other patients were used to evaluate the validity of the DESH-TPM and DESH-Template. DESH-TPM and DESH-Template were created using the 114 well-segmented images after the segmentation processing of CAT12. In the validation study, we compared the accuracy of brain segmentation and spatial normalisation among three conditions: customised condition, applying DESH-TPM and DESH-Template to CAT12 and patient images; standard condition, applying the default setting of CAT12 to patient images; and reference condition, applying the default setting of CAT12 to HC images. RESULTS: In the validation study, we identified three error types during segmentation. (1) The proportions of misidentifying the dura and/or extradural structures as brain structures in the customised, standard, and reference conditions were 10.5%, 44.7%, and 13.6%, respectively; (2) the failure rates of white matter hypointensity (WMH) cancellation in the customised, standard, and reference conditions were 18.4%, 44.7%, and 0%, respectively; and (3) the proportions of cerebrospinal fluid (CSF)-image deficits in the customised, standard, and reference conditions were 97.4%, 84.2%, and 28%, respectively. The spatial normalisation accuracy of grey and white matter images in the customised condition was the highest among the three conditions, especially in terms of superior convexity. CONCLUSIONS: Applying the combination of the DESH-TPM and DESH-Template to CAT12 could improve the accuracy of grey and white matter segmentation and spatial normalisation in patients with DESH. However, this combination could not improve the CSF segmentation accuracy. Another approach is needed to overcome this challenge.

    The applause sign (AS) is a recognized phenomenon observed in progressive supranuclear palsy (PSP) and other neurological conditions where individuals produce over three claps following a request to clap only thrice after a demonstration. In this study, we introduced a novel linguistic phenomenon termed the oral applause sign (OAS) associated with the AS. The OAS is characterized by increased repetition counts of Japanese repetitive onomatopoeic words, such as uttering "pata-pata-pata" instead of the expected "pata-pata." We identified this phenomenon in a patient with PSP exhibiting the AS and mild apraxia of speech. In addition, we developed the three-"pata" test, instructing the patient to say "pata" only thrice after demonstration without any semantic context, and reproduced the phenomenon of the additional increase of "pata" verbalization. The core feature of OAS is an inability to limit the count when repeating a small number of syllables continuously, similar to the inability to stop clapping. The shared features between the OAS and AS suggest potential overlapping mechanisms involving the dysfunction of the frontal lobe and subcortical structures and possibly, apraxia of speech. Considering that the OAS is triggered purely by repetition and unlikely to be affected by semantic content, it might be observable in Japanese and other languages. Longitudinal studies with larger cohorts across various neurodegenerative diseases and languages may elucidate the underlying mechanisms of the OAS and confirm its specificity to PSP, thus improving the generalizability and clinical relevance of the findings.

    OBJECTIVE: To investigate the prevalence and intensity of grasp reflexes and to examine changes in these reflexes after shunt surgery in patients with idiopathic normal pressure hydrocephalus (iNPH). METHODS: We enrolled 147 patients with probable iNPH. A standard procedure was used to determine the presence of grasp reflexes, and the intensity of these reflexes was assessed using a four-category classification. Clinical rating scales and their correlation with grasp reflexes were also evaluated. Grasp reflexes were reassessed in 72 patients 1 year after surgery. RESULTS: We found that approximately 50.3% of patients with iNPH exhibited a positive grasp reflex. Among these patients, 69% exhibited bilateral positivity, while the remaining patients showed unilateral positivity. Furthermore, the intensity of the grasp reflex was significantly correlated with the severity of gait and with cognitive, urinary, motor, and behavioural symptoms. Surgical interventions led to a reduction (41.7%) or maintenance (30.6%) of the reflex intensity in 72.3% of iNPH patients. The changes in reflex intensity showed significant positive correlations with changes in the number of steps of the Timed Up and Go test and Trail Making Test-A scores but not with changes in total scores on the iNPH Grading Scale. CONCLUSION: This retrospective study identified grasp reflexes as a highly prevalent phenomenon in patients with iNPH. These reflexes can assist in evaluating the severity of various symptoms, including cognitive, gait, urinary, motor and emotional symptoms.

    Buccofacial apraxia (BFA) is associated with nonfluent/agrammatic variant primary progressive aphasia (nfvPPA) as well as with the severity of apraxia of speech (AOS), a core symptom of nfvPPA. However, an association with agrammatism has not been established. The aim of this study was to examine the association between BFA and agrammatism in nfvPPA and to determine differences in atrophic regions in primary progressive aphasia (PPA) with and without BFA. Seventy-four patients with PPA were recruited, including 34, 15, 10, and 15 patients with nfvPPA, semantic variant PPA, logopenic variant PPA, and unclassified PPA, respectively. All patients underwent language examination and BFA evaluations. Voxel-based morphometry (VBM) was performed to determine whether atrophy of a specific lesion correlated with the presence of BFA. BFA was observed in 20 and 3 patients with nfvPPA and unclassified PPA, respectively. In a comparison of patients with nfvPPA with and without BFA, the BFA group showed significantly worse spontaneous speech and writing in the Western Aphasia Battery. The agrammatism ratio or the ratio of agrammatic errors to the total number of particles was higher in the BFA group; however, the severity of prosodic and phonetic components of AOS did not differ between the two groups. VBM showed that the severity of BFA correlated with atrophy of the opercular and triangular areas of the inferior frontal gyrus to a part of the left middle frontal gyrus. BFA has a different anatomical basis from AOS in patients with nfvPPA and that BFA is characterized by more anterior degeneration compared to that of AOS.

    The Wada test is the gold standard for determining language-dominant hemisphere. However, the precise determination of language areas in each patient requires more invasive methods, such as electrocortical stimulation. Some studies have reported the use of anesthetic injection into selective cerebral arteries to predict postoperative function. To assess the function of the anterior and posterior language areas separately, we developed an advanced test named the "super-selective Wada test" (ssWada). The ssWada procedure is as follows: an endovascular neurosurgeon identifies the arterial branches of the middle cerebral artery (MCA) perfusing the anterior language area of the inferior frontal gyrus and the posterior language area of the posterior part of the superior temporal gyrus using angiography. Behavioral neurologists assess language symptoms before and after propofol administration using a microcatheter tip in the selected arterial branch. From 30 serial patients with epilepsy who underwent ssWada test at Tohoku University Hospital, we retrospectively reviewed patients in whom multiple areas in the bilateral MCA region was examined. Eight cases were identified in this study. All eight cases had been considered for resection of the area overlapping the classical language area. Three of the eight cases were left-dominant, and the within-hemisphere distribution was also considered typical. One case was determined to be left-dominant but atypical in the intra-hemispheric functional distribution. Two cases were right-dominant, and the intra-hemispheric functional distribution was considered a mirror image of the typical pattern. The remaining two cases were considered atypical, not only in terms of bilateral language function, but also in terms of anterior-posterior functional distribution. This case series demonstrates the potential utility of ssWada in revealing separate function of the anterior and posterior language areas. The ssWada allows simulation of local surgical brain resection and detailed investigation of language function, which potentially contributes to planning the resection area. Although indications for ssWada are quite limited, it could play a complementary role to noninvasive testing because it provides information related to resection using a different approach.

    OBJECTIVE: This study aimed to examine echolalia and its related symptoms and brain lesions in primary progressive aphasia (PPA). METHODS: Forty-five patients with PPA were included: 19 nonfluent/agrammatic variant PPA (nfvPPA), 5 semantic variant PPA, 7 logopenic variant PPA, and 14 unclassified PPA patients. We detected echolalia in unstructured conversations. An evaluation of language function and the presence of parkinsonism, grasp reflex, imitation behaviour, and disinhibition were assessed. We also measured regional cerebral blood flow (rCBF) using single-photon emission computed tomography. RESULTS: Echolalia was observed in 12 nfvPPA and 2 unclassified PPA patients. All patients showed mitigated echolalia. We compared nfvPPA patients with echolalia (echolalia group) to those without echolalia (non-echolalia group). The median age of the echolalia group was significantly lower than that of the non-echolalia group, and the echolalia group showed a significantly worse auditory comprehension performance than the non-echolalia group. In contrast, the performance of repetition tasks was not different between the two groups. The prevalence of imitation behaviour in the echolalia group was significantly higher than that in the non-echolalia group. The rCBFs in the bilateral pre-supplementary motor area and bilateral middle cingulate cortex in the echolalia group were significantly lower than those in the non-echolalia group. CONCLUSIONS: These findings suggest that echolalia is characteristic of nfvPPA patients with impaired comprehension. Reduced inhibition of the medial frontal cortex with release activity of the anterior perisylvian area account for the emergence of echolalia.

    <p>We report a patient with progressive word deafness and foreign accent syndrome. The patient is 70-years-old right-handed female. Although pure tone audiometry is normal, speech audiometry is impaired. Her speech occasionally shows sound errors and omission or misuse of postpositional particles, and is perceived by listeners as foreign. There are not any other cognitive deterioration and aphasia including comprehension of sentences with complex syntax. The most prominent feature of her speech is abnormality of prosody, although abnormality of accent and segmentation of sounds are also apparent. MRI of the brain revealed atrophy of the right superior temporal gyrus and Heschl's gyrus. IMP-SPECT showed bilateral frontotemporoparietal hypoperfusion, particuraly in the right hemisphere. The responsible lesions may be bilateral peri-Sylvius region with an emphasis on the right hemisphere. There would be cases with progressive word deafness and speech disorders as a subtype of progressive aphasia.</p>

    In this study, we investigated the features of apraxia of speech in patients with non-fluent/agrammatic variant primary progressive aphasia (nfvPPA). We conducted auditory impression assessments and acoustic analyses. The findings suggest that the Apraxia of Speech Rating Scale-3 Japanese version might be useful in assessing the presence of sound distortions and segmentation in auditory impression assessments. Acoustic analyses revealed that in the nfvPPA group, there were lower correlation coefficients in sound pressure waves and smaller changes in fundamental frequency compared to the healthy control group. However, no significant differences were observed regarding indicators of sound distortion. Further investigation will clarify the usefulness of indices in acoustic analyses.
