Autobiographical memory is intrinsically related to the self and personal identity. This study investigated whether both personal episodic memory and semantic memory are impaired in schizophrenia, a disease characterized by an abnormal personal identity. Personal episodic memory and personal semantic memory were investigated in 24 patients with schizophrenia and 24 normal subjects using an autobiographical fluency task and an autobiographical memory inquiry. Autobiographical memory scores and the proportion of specific memories were lower in patients with schizophrenia than in normal subjects. The deficit of personal episodic and semantic memory, as assessed by the autobiographical memory inquiry and the autobiographical fluency task, respectively, was most apparent after the onset of clinical symptoms. Schizophrenia is associated with an impairment of both personal episodic and semantic memory and with a reduction of specific autobiographical memories. Those impairments are consistent with the existence of an abnormal personal identity in patients with schizophrenia.
"occurring at the retrieval phase in schizophrenia. In fact, dysfunctions of cognitive processes involved at the encoding phase (Riutort et al., 2003; Danion et al., 2007) or in the storage and organization phase may also contribute to patients' autobiographical memory deficits (Morise et al., 2011; Bennouna-Greene et al., 2012). Although rumination and autobiographical memory impairment showed no direct relationship in patients, both may point to a metacognitive dysfunction, which refers to difficulties recognizing mental states, naming them correctly and using them in a flexible way (Dimaggio et al., 2012; Lysaker et al., 2014).

[Show abstract][Hide abstract] ABSTRACT: Although patients with schizophrenia exhibit autobiographical memory impairment, which is considered to be a limiting factor in their daily life, the mechanisms underlying such impairment have been rarely studied. In the current study, we investigate whether rumination and, in particular, brooding, which is a form of maladaptive repetitive thinking, may be linked to the difficulty that patients with schizophrenia experience when attempting to access specific autobiographical memories. Our results indicate that patients reported less specific autobiographical memories compared to control participants. Patients also displayed a higher level of brooding and had more depressive symptoms. According to the CaR-FA-X model (Williams et al., 2007), depression and brooding were associated with memory specificity in control participants. In contrast, neither depression nor brooding was correlated with memory specificity in patients. These results suggest that depression and rumination may not be directly related to patients' difficulty to recall specific memories and that other factors, such as metacognitive deficits, must first be considered when seeking interventions aimed to improve autobiographical memory in patients with schizophrenia.

"Across studies, in all periods of life, people with schizophrenia consistently demonstrate lower specificity in autobiographical memory recall than controls (Corcoran and Frith 2003; D 0 Argembeau et al. 2008; Feinstein et al. 1998; Neumann et al. 2007). This impairment is highest following illness onset (Elvevag et al. 2003; Riutort et al. 2003), reflecting encoding or acquisition problems after diagnosis (Danion et al. 2005), although semantic processing is sufficient to benefit from organizational cues (Ragland et al. 2003).

[Show abstract][Hide abstract] ABSTRACT: Autobiographical recall training in people with
schizophrenia may have positive effects on social functioning,
mood state, or imagination of future events. Thirtytwo
stabilized participants with schizophrenia were randomly
assigned to two groups. One group completed a
program of life review training based on positive events
(LRTspev), while the other group continued with their
usual treatment. LRTspev consisted of structured interviews
exploring positive past events from childhood, adolescence,
adulthood, and last year. After treatment, the
LRTspev group showed increased numbers of specific
memories and details of the recalled events. However, no
changes in symptoms of depression and brooding (negative
repetitive thinking) were observed. Limitations and future
recommendations to increase cognitive behavioral therapy
efficiency based on autobiographical information recovery
for people with schizophrenia are discussed.

"Por tanto, la MA podría considerarse como una parte inherente de la identidad personal, fuertemente relacionada con su desarrollo y fundamental para dotar de continuidad al yo, para el desarrollo y mantenimiento de las relaciones con los otros y, para la resolución de problemas (Conway y Pleydell- Pearce, 2000). Pero, a pesar de esta clara relación entre la MA y la definición de la propia identidad, se han diseñado pocos estudios para evaluar el entrenamiento en MA en pacientes con esquizofrenia, un trastorno caracterizado por una identidad personal alterada (Riutort et al., 2003). Las intervenciones para mejorar la MA en la esquizofrenia deben centrarse en dotar al individuo de una mayor coherencia del yo, reducir los niveles de confusión respecto a la fuente que proporciona el recuerdo y evitar llegar a conclusiones precipitadas debido a un análisis superficial de la información (Ricarte, Hernández-Viadel, Latorre y Ros, 2012). "
[Show abstract][Hide abstract] ABSTRACT: This study aimed to evaluate the efficacy of the Life Therapy Review (LTR) and the Significant Specific Life Events Therapy (SSLET) on the autobiographical memories and the mood state in patients with schizophrenia. 30 patients with schizophrenia were randomly assigned to a LTR group (n= 15) or SSLET group (n=15). Evaluations were made before and after treatment. The results show that both therapies increase autobiographical memory specificity. On the other hand, depressive symptoms only improve in SSLET group. This study provides evidence that autobiographical memory can be trained in schizophrenia, which allows to improve the capacity to encode and store new information. This improvement reduces source attributing mistakes.
