Abstract

Background Tuberous sclerosis complex is a multisystem genetic disorder with a range of physical manifestations that require evaluation, surveillance, and management. Individuals with tuberous sclerosis complex also have a range of behavioral, psychiatric, intellectual, academic, neuropsychologic, and psychosocial difficulties. These may represent the greatest burden of the disease. Around 90% of individuals with tuberous sclerosis complex will have some of these difficulties during their lifetime, yet only about 20% ever receive evaluation and treatment. The Neuropsychiatry Panel at the 2012 Tuberous Sclerosis Complex International Consensus Conference expressed concern about the significant "treatment gap" and about confusion regarding terminology relating to the biopsychosocial difficulties associated with tuberous sclerosis complex. Methods The Tuberous Sclerosis Complex Neuropsychiatry Panel coined the term TAND-tuberous sclerosis complex-associated neuropsychiatric disorders-to bring together these multidimensional manifestations of the disorder, and recommended annual screening for TAND. In addition, the Panel agreed to develop a TAND Checklist as a guide for screening. Results Here, we present an outline of the conceptualization of TAND, rationale for the structure of the TAND Checklist, and include the full US English version of the TAND Checklist. Conclusion We hope that the unified term TAND and the TAND Checklist will raise awareness of the importance of tuberous sclerosis complex-associated neuropsychiatric disorders and of the major burden of disease associated with it, provide a shared language and a simple tool to describe and evaluate the different levels of TAND, alert clinical teams and families or individuals of the importance of screening, assessment, and treatment of TAND, and provide a shared framework for future studies of tuberous sclerosis complex-associated neuropsychiatric disorders.

  • Development of the TAND checklist was necessary because 90% of patients with TSC endorsed neuropsychiatric symptoms, yet only 20% received treatment.

    “Development of the TAND checklist was necessary because 90% of patients with TSC endorsed neuropsychiatric symptoms, yet only 20% received treatment.11”

    From Association of Cognitive and Behavioral Features Between Adults With Tuberous Sclerosis and Frontotemporal Dementia (2020) · cites this paper as [11]

    The Introduction links development of the TAND Checklist to a substantial treatment gap: more than 90% of individuals with TSC were likely to have relevant challenges, while only 18% of surveyed families had ever received recommended evaluations or treatments. It does not say that 90% of patients endorsed symptoms or that 20% received treatment; those figures change both what was measured and who was counted. (LLM, conf=0.88)

  • Individuals with TSC commonly experience a wide spectrum of cognitive, behavioral and psychiatric symptoms collectively known as Tuberous Sclerosis Complex Associated Neuropsychiatric Disorders (TAND).

    “Individuals with TSC commonly experience a wide spectrum of cognitive, behavioral and psychiatric symptoms collectively known as Tuberous Sclerosis Complex Associated Neuropsychiatric Disorders (TAND) (5).”
  • Patients with TSC frequently suffer from behavioral, cognitive and psychiatric difficulties collectively termed TAND.

    “In addition to the physical manifestations of TSC, these patients frequently suffer from behavioral, cognitive and psychiatric difficulties collectively termed Tuberous Sclerosis Complex Associated Neuropsychiatric disorders (TAND) [14].”
  • The TAND checklist serves as a clinical screening tool to assess neuropsychiatric difficulties that include the behavioral, cognitive and psychiatric domains.

    “The TAND checklist serves as a clinical screening tool to assess neuropsychiatric difficulties that include the behavioral, cognitive and psychiatric domains.11”
  • Prior reports depict tau-related changes as elevated p-tau staining in the absence of frank neurofibrillary tangles.

    “Generally, prior reports depict tau-related changes as elevated p-tau staining in the absence of frank neurofibrillary tangles.”

    From Tuberous sclerosis complex is associated with a novel human tauopathy (2023) · cites this paper as [6]

    The Introduction discusses mTOR signaling and neuropsychiatric difficulties in tuberous sclerosis, not tau pathology. Searches for p-tau staining and neurofibrillary tangles found no passage in our copy addressing either finding; page numbers were unavailable. (LLM, conf=0.76)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
