Front Neurosci 2023; 17:1198409. [PMID: 37250398 PMCID: PMC10211341 DOI: 10.3389/fnins.2023.1198409] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2023] [Accepted: 04/24/2023] [Indexed: 05/31/2023] Open
Abstract
Background Emerging evidence has been reported of attentional dysfunction in pituitary adenoma patients. However, the effect of pituitary adenomas on lateralized attention network efficiency remained to be clear. Thus, the present study aimed to investigate the impairment of lateralized attention networks in patients with pituitary adenoma. Methods Eighteen pituitary adenoma patients (PA group) and 20 healthy controls (HCs) were included in this study. Both behavioral results and event-related potentials (ERPs) were acquired while subjects performed the Lateralized Attention Network Test (LANT). Results Behavioral performances indicated the PA group had a slower reaction time and a similar error rate relative to the HCs group. Meanwhile, significantly increased executive control network efficiency suggested the dysfunction of inhibition control in PA patients. Regarding ERP results, there were no group differences in the alerting and orienting networks. The target-related P3 was significantly reduced in the PA group, suggesting an impairment of executive control function and attentional resources allocation. Moreover, the mean amplitude of P3 was significantly lateralized to the right hemisphere, and interacted with the visual field, exhibiting that the right hemisphere dominated the bilateral visual field, whereas the left hemisphere dominated the left visual field. In the specific high-conflict condition, the pattern of hemispheric asymmetry in the PA group was altered due to a mixed effect resulting from the compensatory recruitment of attentional resources in the left central parietal area and the destructive effects of hyperprolactinemia. Conclusion These findings suggested that, in the lateralized condition, the decreased P3 in the right central parietal area and the diminished hemispheric asymmetry under high conflict load, may serve as the potential biomarkers of attentional dysfunction in patients with pituitary adenoma.

Hyperprolactinemia Associated with Attentional Processing and Interference Control Impairments in Patients with Prolactinomas. Brain Sci 2022; 12:brainsci12081091. [PMID: 36009154 PMCID: PMC9406026 DOI: 10.3390/brainsci12081091] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Revised: 08/10/2022] [Accepted: 08/13/2022] [Indexed: 11/25/2022] Open
Abstract
The cognitive impairment of pituitary adenomas (PAs) has received increasing attention. Hyperprolactinemia and tumor mass effect are the potential causes. The aim of this study was to identify possible cognitive impairment and to further explore the correlation between these indices and prolactin (PRL) levels, based on the control of tumor size. Twenty-seven patients with prolactinomas (patient group) and twenty-six matched health control group (HC group) were enrolled in this study. All participants performed the flanker task while we continuously recorded electroencephalography data. On the behavioral performance level, patients showed a significantly slower reaction time (RT) in both flanker types. Concerning the event-related potentials level, patients elicited reduced P2 and enhanced N2 amplitudes compared with the HC group, suggesting an impairment of attentional processing (P2) and conflict monitoring (N2). Moreover, the patient group also induced lower P3 amplitudes relative to the HC group in both types, indicating that there were deficits in attentional resource allocation ability. We also found a significant correlation between the P3 amplitudes and incongruent condition RTs, as well as the subsequent PRL levels in the patient group. In conclusion, this is an innovative study that reveals the impaired cognition abilities in prolactinomas, and also proposes the possible cognitive toxicity of oversecreted PRL levels, which provides evidence for further research on the cognitive decline in PAs.

Impaired quality of life, but not cognition, is linked to a history of chronic hypercortisolism in patients with Cushing's disease in remission. Front Endocrinol (Lausanne) 2022; 13:934347. [PMID: 36004342 PMCID: PMC9393704 DOI: 10.3389/fendo.2022.934347] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2022] [Accepted: 07/15/2022] [Indexed: 11/13/2022] Open
Abstract
CONTEXT Impaired cognition and altered quality of life (QoL) may persist despite long-term remission of Cushing's disease (CD). Persistent comorbidities and treatment modalities may account for cognitive impairments. Therefore, the role of hypercortisolism per se on cognitive sequelae remains debatable. OBJECTIVE To investigate whether memory and QoL are impaired after long-term remission of CD in patients with no confounding comorbidity. DESIGN AND SETTING Cross-sectional case-control study in two tertiary referral centers. PATIENTS 25 patients (44.5 ± 2.4 years) in remission from CD for 102.7 ± 19.3 Mo and 25 well-matched controls, without comorbidity or treatment liable to impair cognition. MAIN OUTCOME MEASURES Hippocampus- and prefrontal cortex-dependent memory, including memory flexibility and working memory, were investigated using multiple tests including sensitive locally-developed computerized tasks. Depression and anxiety were evaluated with the MADRS and HADS questionnaires. QoL was evaluated with the SF-36 and CushingQoL questionnaires. The intensity of CD was assessed using mean urinary free cortisol and a score for clinical symptoms. RESULTS CD patients displayed similar performance to controls in all cognitive tests. In contrast, despite the absence of depression and a minimal residual clinical Cushing score, patients had worse QoL. Most of the SF36 subscales and the CushingQoL score were negatively associated only with the duration of exposure to hypercortisolism (p≤ 0.01 to 0.001). CONCLUSIONS Persistent comorbidities can be a primary cause of long-lasting cognitive impairment and should be actively treated. Persistently altered QoL may reflect irreversible effects of hypercortisolism, highlighting the need to reduce its duration.

Abstract
Neurocognitive complaints are common in patients with pituitary tumours, particularly in memory and concentration. Past studies have shown impairments in executive function and memory, but it is not clear whether these result from direct effects of the tumour (pressure or hormonal secretion), incidental damage from radiotherapy or surgical treatments, and/or mediating psychiatric factors. This study assessed cognitive function and psychiatric state of 86 pituitary tumour patients and 18 healthy controls, pre and post-treatment, to examine the effects of tumour aetiology and treatment type. No significant cognitive impairments were found, except on verbal recognition memory. Patients with Cushing's disease showed lower verbal recognition memory than the other groups pre-treatment, but improved at follow-up. This was (at least partially) accounted for by an improvement in depression scores. Patients who were treated with surgery showed poorer verbal recognition memory than controls across all (pre- and post-treatment) time-points. Overall findings of minimal cognitive impairment in patients with pituitary tumours may reflect improved diagnostic and treatment techniques in recent years. We suggest that the verbal memory impairments identified in the Cushing's group may result from increased cortisol (directly, or mediated by depression). In the surgical groups, verbal memory impairments appeared to pre-date treatment. This may relate to treatment selection factors, rather than harmful effects of surgery itself.

Abstract
OBJECTIVE Some studies have highlighted psychological and neuropsychological difficulties and a potential reduction in health-related quality of life (HRQOL) in patients with pituitary tumors, despite hormone deficits or excess. To the authors' knowledge, this study is the first prospective longitudinal case-control study with the aim of simultaneously testing whether HRQOL and psychiatric and neuropsychological disabilities are related to neural dysfunction due to hypercortisolism per se, or tumor mass and/or surgery in patients with Cushing's disease (CD). The authors evaluated a homogeneous cohort of patients with CD and nonfunctioning pituitary adenomas (NFPAs) before and after neurosurgery and compared these patients with healthy controls. METHODS Twenty patients (10 with NFPA and 10 with CD) were evaluated using 3 validated questionnaires (SF-36, Beck Depression Inventory-II [BDI-II], and Minnesota Multiphasic Personality Inventory-II [MMPI-II]) to assess HRQOL and psychological status preoperatively and 12 months after neurosurgery. Neuropsychological tests were assessed preoperatively, 3-7 days postoperatively, and 12 months postoperatively. Twenty healthy matched controls were recruited. RESULTS Preoperatively, the NFPA and CD subgroups had worse HRQOL scores than controls on the basis of SF-36 scores, although the NFPA subgroup experienced significant recovery 12 months postoperatively. Preoperatively, CD patients had depressive symptoms according to the BDI-II and MMPI-II that persisted 12 months postoperatively, together with social introversion and hypochondriasis; NFPA patients were similar to controls except for hypochondriasis scores that were clinically significant at all timepoints. Preoperatively and 3-7 days postoperatively, both subgroups showed significant neuropsychological disabilities compared with controls, but only the CD subgroup did not completely recover over time. CONCLUSIONS HRQOL and neuropsychological impairments were observed in all patients at early timepoints, independent of hypercortisolism, tumor mass, and successful surgery. Over time, CD patients showed persistent changes in HRQOL, in particular in social activities. In this light, CD seems to have a strong impact on HRQOL and to be associated with more psychological and neuropsychological comorbidities than NFPA.

Abstract
OBJECTIVEPituitary adenomas and the treatment required for the underlying neuropathology have frequently been associated with cognitive dysfunction. However, the mechanisms for these impairments remain the subject of much debate. The authors evaluated cognitive outcomes in patients treated with or without Gamma Knife radiosurgery (GKRS) for an underlying pituitary adenoma.METHODSThis was a retrospective, institutional review board-approved, single-institution study. A total of 51 patients (23 male, 28 female) treated for pituitary adenoma were included in this neurocognitive study. Twenty-one patients underwent GKRS following transsphenoidal surgery, 22 patients were treated with transsphenoidal surgery alone, and eight patients were conservatively managed or were treated with medical management alone. Comparisons using psychometric tests of general intellectual abilities, memory, and executive functions were made between the treatment groups, between male and female patients, and between patients with Cushing's disease and those with nonfunctioning adenoma (NFA).RESULTSThe entire patient sample, the NFA group, and the GKRS group scored significantly below expected on measures of both immediate and delayed memory, particularly for visually presented information (p ≤ 0.05); however, there were no significant differences between the patients with Cushing's disease and those with NFA (t ≤ 0.56, p ≥ 0.52). In those who underwent GKRS, memory scores were not significantly different from those in the patients who did not undergo GKRS (t ≤ 1.32, p ≥ 0.19). Male patients across the sample were more likely to demonstrate impairments in both immediate memory (t = -3.41, p = 0.003) and delayed memory (t = -3.80, p = 0.001) than were female patients (t ≤ 1.09, p ≥ 0.29). There were no impairments on measures of general intellectual functioning or executive functions in any patient group. The potential contributions of tumor size and hormone levels are discussed.CONCLUSIONSOverall, pituitary adenoma patients demonstrated relative impairment in anterograde memory. However, GKRS did not lead to adverse effects for immediate or delayed memory in pituitary adenoma patients. Cognitive assessment of pituitary adenoma patients is important in their longitudinal care.

Abstract
OBJECTIVE Patients with nonfunctioning pituitary adenomas (NFPAs) can suffer from cognitive dysfunction. However, the literature on longitudinal cognitive follow-up of patients undergoing endoscopic endonasal transsphenoidal surgery (EETS) is limited. This study was performed to investigate perioperative cognitive status and course in patients with NFPAs. METHODS Patients underwent computerized neuropsychological assessment 1 day before (n = 45) and 3 months after (n = 36) EETS. Performance in 7 domains was measured with a computerized test battery (CNS Vital Signs) and standardized using data from a healthy control group. The authors conducted analyses of cognitive performance at both time points and changes pre- to post-ETSS on a group and an individual level. Linear multiple regression analyses were employed to investigate predictors of cognitive performance. RESULTS On average, patients scored significantly lower in 6 of 7 cognitive domains before and after surgery than controls. Impairment proportions were significantly higher among patients (56% before surgery, 63% after surgery) than among controls. Patients showed no change over time in group-level (mean) performance, but 28% of individual patients exhibited cognitive improvement and 28% exhibited cognitive decline after surgery. Hormonal deficiency showed a positive correlation with verbal memory before surgery. Postoperative performances in all cognitive domains were predicted by preoperative performances. CONCLUSIONS Cognitive impairment was present before and after EETS in over half of NFPA patients. Individual patients showed diverse postoperative cognitive courses. Monitoring of cognitive functioning in clinical trajectories and further identification of disease-related and psychological predictors of cognition are warranted.

Abstract
BACKGROUND Cognitive impairments have been reported in patients with pituitary adenomas (PAs). The aim of this research was to demonstrate the effects of hormones and age on cognitive decline in patients with PAs. METHODS A total of 64 patients with PA and 69 healthy control subjects (HCs) were recruited for this study. Both PAs and HCs were divided into a younger group (<50 years of age) and an older group (≥50 years of age). Neurocognitive domains were assessed using the Wechsler Adult Intelligence Scale-Chinese Revision (WAIS-RC) and Wechsler Memory Scale-Chinese Revision (WMS-RC) tests. Furthermore, we also investigated the relationship between cognitive domains and tumor volume, and the hormone levels and age of patients with PA. RESULTS Several of the cognitive impairments found on the WAIS-RC and WMS-RC tests were more frequently observed in untreated patients with PA. Importantly, no significant correlations were found between cognitive domains and tumor volume after controlling age, sex, and educational levels. Furthermore, several significant correlations were found between cognitive domains and hormone levels, such as free thyroxine and adrenocorticotropic hormone, after controlling age, sex, and educational levels. Finally, the age of the patients was found to correlate with a decrease in memory after controlling sex and educational levels. CONCLUSIONS Our findings demonstrate a significant decline in the cognitive performance of patients with PA prior to medical treatment, especially in older patients, which suggests that hormones and age have the ability to interact and aggravate cognitive decline in patients with PA.

Abstract
Despite characteristic symptoms the diagnosis of clinically relevant pituitary adenomas is often delayed until an advanced stage due to the rarity of the disease. The typical clinical manifestations are presented in this review article. The recent discovery of the USP8 mutation in Cushing's disease and of X‑linked acrogigantism (X-LAG) syndrome in early onset gigantism were milestones in the search for the molecular etiology of pituitary adenomas. The triad of endocrinological, radiological and ophthalmological diagnostics are the main pillars for the diagnostic work-up of pituitary adenomas. The standard treatment modalities, which include surgery, medical treatment and irradiation, have been further developed and refined. For transsphenoidal excision of pituitary adenomas, microsurgery and endoscopy are two equivalent surgical techniques with relatively few complications. Surgery represents the first-line treatment of pituitary adenomas. Prolactinomas are an exception as the medical treatment with dopamine agonists is highly efficient. Nowadays, new medical treatment options are available for acromegaly and Cushing's disease and are used for second-line treatment. The alkylating chemotherapeutic agent temozolomide is used for the first-line chemotherapy of rare aggressively growing pituitary adenomas. Irradiation is indicated if surgical and medical treatment options are insufficiently successful. Stereotactic one-stage irradiation (radiosurgery) is especially suitable for well-demarcated invasive residual or recurrent adenomas in the cavernous sinus. A new development is hypofractionated radiosurgery for protection of structures at risk. Fractionated irradiation is necessary with large radiation volumes and for pituitary adenomas with a close proximity to the optic tract.

Abstract
Pituitary tumor is an intracranial tumor; because of the development of neuroimaging technology in recent years, morbidity is likely to increase. Evidence showed impaired cognitive ability of patients with pituitary adenoma. There is evidence that neurobehavioral disorders are common in pituitary adenoma patients. This disorder is because of the cognitive and emotional function of the important functional areas of the brain oppressed and hormone imbalance. Individuals' mental activity is controlled by the brain and the abnormal mental activity is caused by both the structural abnormalities of the brain and neurochemical dysfunction. Event-related potentials have been used widely in the early assessment of cognitive functions associated with disease, taking advantage of the high temporal resolution, and then analyzing the characteristics of emotional competence from the perspective of cognitive processing. A visual Go/Nogo task was used. A larger Nogo-N2 and Nogo-P3 was found in the control group compared with the pituitary group. This reflects the nonphysiological process of conflict monitoring and inhibitory control in pituitary patients. The results also showed that the difference waves between Go and Nogo conditions (N2d and P3d) over the frontal electrode sites were more robust and earlier in the control group compared with the pituitary group, which reflects frontal dysfunction in the pituitary group. These data suggest reduced earlier and later stages of inhibitory processes in pituitary individuals, implicating the dysfunction of conflict detection and inhibitory control.

Abstract
BACKGROUND There have been no studies investigating the correlation between structural [thickness of the retinal nerve fiber layer (RNFL) as determined by optical coherence tomography (OCT)] and functional [Humphrey visual field (HVF) or visual evoked potential (VEP) amplitude] measures of optic nerve integrity in patients with pituitary adenomas (PA). METHODS Patients with PAs were recruited between September 2010 and September 2013. OCT, standard automated perimetry (SAP), and multifical VEP (mfVEP) were performed. Agreement between OCT, SAP, and mfVEP values in classifying eyes/quadrants was determined using AC1 statistics. Pearson's correlation was used to examine relationships between structural and functional data. RESULTS In total, 88.7% of the eyes tested showed abnormal SAP findings and 93.7% showed abnormal mfVEP findings. Only 14.8% of the eyes showed abnormal OCT findings. The agreement between SAP and mfVEP findings was 88.9% (AC1 = 0.87). The agreement between OCT and mfVEP findings was 24.2% (AC1 = -0.52), and that between OCT and SAP findings was 21.5% (AC1 = -0.56). The correlation values between RNFL thickness and the functional measurements were -0.601 for the mfVEP score (P = 0.000) and -0.441 for the SAP score (P = 0.000). The correlation between the mfVEP and SAP scores was -0.617 (P = 0.000). CONCLUSIONS mfVEP, SAP, and OCT provided complementary information for detecting visual pathway abnormalities in patients with PAs. Good agreement was demonstrated between SAP and mfVEP and quantitative analysis of structure-function measurements revealed a moderate correlation.

Abstract
ABSTRACT Aim: Pituitary tumors have been found to produce cognitive dysfunctions predominantly related to memory and attention. There exists a potential interaction between surgical and anesthetic factors in producing cognitive changes. Therefore we aim to investigate the incidence of cognitive decline and role of nitrous oxide (N2O) on immediate cognitive changes in patients undergoing transsphenoidal removal of pituitary tumors. Patients & methods: Ninety patients between 18 and 65 years of age, undergoing transsphenoidal surgery for pituitary tumor removal, were enrolled and divided into two (air and N2O-based anesthetic regime) groups. Cognitive functions were noted using the Hindi Mini Mental State Examination at baseline and three times in the postoperative period (1-h, 24-h postextubation and at the time of hospital discharge). Results: Both groups were comparable with respect to demographics, baseline parameters and cognitive scores. Significant number of patients (73%) showed cognitive decline in both the groups within 24 h postoperatively. In the factor analysis, thyroid-stimulating hormone and fentanyl consumption were linked with changes in cognitive scores. Conclusion: Patients undergoing pituitary surgery have significantly immediate cognitive decline in the short followup, but N2O-based anesthesia alone does not increase the risk of postoperative cognitive decline.
