Abstract
Chiari malformation has been classified as a group of posterior cranial fossa disorders characterized by hindbrain herniation. Chiari malformation type I (CM-I) is the most common subtype, ranging from asymptomatic patients to those with severe disorders. Research about clinical manifestations or medical treatments is still growing, but cognitive functioning has been less explored. The aim of this systematic review is to update the literature search about cognitive deficits in CM-I patients. A literature search was performed through the following electronic databases: MEDLINE, PsychINFO, Pubmed, Cochrane Library, Scopus, and Web of Science. The date last searched was February 1, 2023. The inclusion criteria were as follows: (a) include pediatric or adult participants with a CM-I diagnosis, (b) include cognitive or neuropsychological assessment with standardized tests, (c) be published in English or Spanish, and (d) be empirical studies. Articles that did not report empirical data, textbooks and conference abstracts were excluded. After the screening, twenty-eight articles were included in this systematic review. From those, twenty-one articles were focused on adult samples and seven included pediatric patients. There is a great heterogeneity in the recruited samples, followed methodology and administered neurocognitive protocols. Cognitive functioning appears to be affected in CM-I patients, at least some aspects of attention, executive functions, visuospatial abilities, episodic memory, or processing speed. However, these results require careful interpretation due to the methodological limitations of the studies. Although it is difficult to draw a clear profile of cognitive deficits related to CM-I, the literature suggests that cognitive dysfunction may be a symptom of CM-I. This suggest that clinicians should include cognitive assessment in their diagnostic procedures used for CM-I. In summary, further research is needed to determine a well-defined cognitive profile related to CM-I, favoring a multidisciplinary approach of this disorder.

Abstract
BACKGROUND Chiari I malformation (CIM) is characterized by descent of the cerebellar tonsils through the foramen magnum, potentially causing symptoms from compression or obstruction of the flow of cerebrospinal fluid. Diagnosis and treatment of CIM is varied, and guidelines produced through systematic review may be helpful for clinicians. OBJECTIVE To perform a systematic review of the medical literature to answer specific questions on the diagnosis and treatment of CIM. METHODS PubMed and Embase were queried between 1946 and January 23, 2021, using the search strategies provided in Appendix I of the full guidelines. RESULTS The literature search yielded 430 abstracts, of which 79 were selected for full-text review, 44 were then rejected for not meeting the inclusion criteria or for being off-topic, and 35 were included in this systematic review. CONCLUSION Four Grade C recommendations were made based on Class III evidence, and 1 question had insufficient evidence. The full guidelines can be seen online at https://www.cns.org/guidelines/browse-guidelines-detail/2-symptoms .

Abstract
Chiari malformation type I (CM-I) is a congenital anomaly of the hindbrain. The most common symptoms include suboccipital tussive headache, dizziness and neck pain. Recently there has been growing interest in the psychological and psychiatric aspects of functioning in patients with CM-I, which have a significant effect on treatment outcomes and quality of life (QoL). The aim of the study was to assess the severity of depressive symptoms and the QoL in patients with CM-I and to identify the main factors responsible for these phenomena. A total of 178 people participated in the study and were divided into 3 groups: patients with CM-I who had undergone surgery (n = 59); patients with CM-I who had not undergone surgery (n = 63); and healthy volunteers (n = 56). Psychological evaluation included a set of questionnaires: the Beck Depression Inventory II, the World Health Organization shortened version of the WHOQOL-100 quality of life questionnaire, the Acceptance of Illness Scale and the Beliefs about Pain Control Questionnaire. Results showed that the control group participants obtained significantly better results than both groups of CM-I patients in terms of all indicators of QoL, symptoms of depression, acceptance of illness, pain level (average and present) and perceived influence of doctors regarding coping with pain. Patients with CM-I (operated and non-operated) obtained similar results in most of the questionnaires and the QoL indices correlated significantly with the majority of the analyzed variables. Moreover, CM-I patients with higher depression scores described their pain as more severe and had a stronger belief that pain levels were not influenced by them but only by doctors, or that it could be controlled randomly; they were also less willing to accept their illness. CM-I symptoms affect the mood and QoL of patients. Psychological and psychiatric care should be the golden standard in managing this clinical group.

Abstract
Chiari type 1 malformation (CIM) is defined as tonsillar ectopia of >5 mm, while syringomyelia (SM) is defined as a cerebrospinal fluid (CSF)-filled cavity larger than 3 mm dissecting the spinal cord. Over the last decades, our understanding of these pathologies has grown; however, many controversies still exist almost in every aspect of CIM and SM, including etiology, indication for treatment, timing of treatment, surgical technique, follow-up regime, and outcome. This chapter provides a comprehensive overview on different aspects of CIM and SM and on the still existing controversies, based on the evidence presently available. Future directions for clinical research concerning CIM and SM treatment and outcome are elaborated and discussed as well.

Cognitive and Psychological Functioning in Chiari Malformation Type I Before and After Surgical Decompression - A Prospective Cohort Study. Neurosurgery 2021; 89:1087-1096.

Abstract
BACKGROUND Chiari Malformation Type I (CM-I) is defined as cerebellar tonsil displacement more than 5 mm below the foramen magnum. This displacement can alter cerebrospinal fluid flow at the cervicomedullary junction resulting in Valsalva-induced headaches and syringomyelia and compress the brainstem resulting in bulbar symptoms. However, little is known about cognitive and psychological changes in CM-I. OBJECTIVE To prospectively assess cognitive and psychological performance in CM-I and determine whether changes occur after surgical decompression. METHODS Blinded evaluators assessed symptomatic CM-I patients ages ≥18 with a battery of neuropsychological and psychological tests. Testing was conducted preoperatively and 6 to 18 mo postoperatively. Data were converted to Z-scores based on normative data, and t-tests were used to analyze pre-post changes. RESULTS A total of 26 patients were included, with 19 completing both pre- and post-op cognitive assessments. All patients had resolution of Valsalva-induced headaches and there was improvement in swallowing dysfunction (P < .0001), ataxia (P = .008), and sleep apnea (P = .021). Baseline performances in visual perception and construction (z = -1.11, P = .001) and visuospatial memory (z = -0.93, P = .002) were below average. Pre-post comparisons showed that CM-I patients had stable cognitive and psychological functioning after surgery, without significant changes from preoperative levels. CONCLUSION CM-I patients had below average performance in visuospatial and visuoconstructional abilities preoperatively. Prospective longitudinal data following surgery demonstrated improved neurologic status without any decline in cognition or psychological functioning. Routine pre- and postoperative formal neuropsychological assessment in CM-I patients help quantify cognitive and behavioral changes associated with surgical decompression.
