Cognitive dysfunction and subjective complaints of cancer patients

Psychometric Analysis of the Patient Assessment of Own Functioning Inventory in Women With Breast Cancer

“…Although the number of subjects with clinically meaningful cognitive decline was significantly greater in the substance abuse group, (χ 2 [1] = 25.0, p < .0001), results did not demonstrate that those with clinically meaningful cognitive decline reported more PAOFI complaints ( t [131] = 0.98, p > .05). This phenomenon of lack of correlation between objectively measured cognitive function and subjectively measured reports of cognitive problems is well documented (Iconomou et al, 2004; Kibiger et al, 2003; Poppelreuter et al, 2004). More often, subjectively measured cognitive problems are related to mood, and other self-reported symptoms such as fatigue.…”

“…Because subjective measures may reveal how cognitive impairments affect an individual’s ability to carry on their daily functional activities, such measures have been incorporated into comprehensive neuropsychological assessments when assessing cognitive function (Bender et al, 2008). Self-reports of cognitive problems are more commonly associated with depression, anxiety, and fatigue than they are with scores on objective measures of cognitive function (Poppelreuter et al, 2004). Thus, identification of a reliable and valid self-report measure of subjective cognitive function can be useful clinically to direct nurses to assess whether women with breast cancer who report cognitive problems are also experiencing depression or anxiety, and it can provide valuable information regarding the functional impact of cancer and cancer treatment in this patient population.…”

“…This hypothesis was based on previous findings (Iconomou, Mega, Koutras, Iconomou, & Kalofonos, 2004; Kibiger, Kirsh, Wall, & Passik, 2003; Poppelreuter et al, 2004) that reported that a decline in cognitive functioning is associated with symptoms such as fatigue.…”

Subjective cognitive complaints and neuropsychological test performance following military-related traumatic brain injury

“…Problems with accuracy in selfreported cognitive symptoms are seen in a variety of health conditions, including cognitive functioning after cancer treatment [1], systemic lupus erythematosus [2], epilepsy [3], multiple sclerosis [4], Parkinson disease (PD) [5], and schizophrenia [6]. This reduced accuracy is generally related to overreporting of symptoms, but varies according to the condition.…”

Daños Neuropsicológicos Asociados a los Tratamientos Quimioterapéuticos: Una Propuesta de Evaluación

“…Las pruebas de rendimiento cognitivo podrían no captar el impacto que los afectados perciben en las tareas de su vida diaria (Downi, Mar Fan, Houédé-Tchen, yi y Tannock, 2006); de igual modo, las preguntas generales de screening sobre el daño cognitivo percibido podrían no ser buenas predictoras del daño reflejado por los test neuropsicológicos (López-Santiago, Cruzado, Custodio y Feliu, 2011). Por lo tanto, la evaluación no puede basarse sólo en medidas objetivas o subjetivas (Matsuda et al, 2005;Poppelreuter et al, 2004;Vardy, Xu et al, 2008). Parte del trabajo pendiente es emplear test neuropsicológicos cuyas tareas posean elevada validez ecológica, así como lograr medidas de la percepción de la función cognitiva más específicas.…”
