“…While all types of memory are not yet assessed in meth use disorder, there is strong evidence that both current and abstinent meth users display mild impairments in visual, verbal, and prospective learning and memory (22, 32, 39-41, 43-47, 54, 58-63, 67, 70), even observed after 1.8 years of abstinence ( Table 1). People with schizophrenia display severe impairments in similar domains examined using the same tests (78)(79)(80). Prospective memory impairments are of particular interest because they are negatively associated with treatment outcomes due to poorer adherence to medication regimens (81) and greater likelihood of missed appointments (79).…”

“…Improvements in verbal memory are observed in people with schizophrenia following CRT (158,159). There is also evidence that cognitive training may improve event-based prospective memory in people with schizophrenia (80). Although prospective memory training appears to be a promising treatment approach, effect on daily function and functional outcome has yet to be investigated in schizophrenia.…”

Despite the prevalence of methamphetamine (meth) use disorder, research on meth is disproportionately scarce compared to research on other illicit drugs. Existing evidence highlights cognitive deficits as an impediment against daily function and treatment of chronic meth use. Similar deficits are also observed in schizophrenia, and this review therefore draws on schizophrenia research by examining similarities and differences between the two disorders on cognition and related neural findings. While meth use disorder and schizophrenia are two distinct disorders, they are highly co-morbid and share impairments in similar cognitive domains and altered brain structure/function. This narrative review specifically identifies overlapping features such as deficits in learning and memory, social cognition, working memory and inhibitory/impulse control. We report that while working memory deficits are a core feature of schizophrenia, such deficits are inconsistently observed following chronic meth use. Similar structural and functional abnormalities are also observed in cortical and limbic regions between the two disorders, except for cingulate activity where differences are observed. There is growing evidence that targeting cognitive symptoms may improve functional outcome in schizophrenia, with evidence of normalized abnormal brain activity in regions associated with cognition. Considering the overlap between meth use disorder and schizophrenia, targeting cognitive symptoms in people with meth use disorder may also improve treatment outcome and daily function.

“…The current study was conducted among early adults who were mostly diagnosed with either of clinical diagnosis at an early stage of life. However, there might be differences in PM functioning among individuals who are diagnosed with such illness at a later stage in life or differences in older adults or geriatric population who have a chronic illness (Wang et al, ; Wang, Chan, & Shum, ). Therefore, age is an important factor, and we have not explored a wide range of the population in our study.…”

There is a need to study prospective memory (PM) and its relationship with aspects of frontal lobe functioning in schizophrenia and bipolar disorder. The study aims to investigate event-based (EB) and time-based (TB) PM functioning in the two groups, and its association with working memory, planning, and attention. A word categorisation task was developed to assess PM functioning among 90 participants (schizophrenia, bipolar disorder, and a control group). Frontal lobe functioning was assessed using Tower of London, N-Back test, and triads test. Mean comparisons revealed significantly higher impairment in TB PM in comparison to EB PM in both the clinical groups. Significant relationship between PM and frontal lobe impairment was found. Relationship between PM and frontal lobe deficits in the clinical groups emphasises the need to include its assessment at an early stage and to develop PM rehabilitation strategies to improve the quality of living.

“…Schizophrenia is associated with a wide range of cognitive deficits (Insel, 2010), including prospective memory (PM) impairment (Ordemann, Opper, & Davalos, 2014;Wang, Chan, & Shum, 2017;Wang et al, 2009). PM refers to the ability to remember to carry out intended actions in the future (Einstein & McDaniel, 1990).…”

The beneficial effect of implementation intentions (II) on prospective memory (PM) deficits in patients with schizophrenia has been reported. However, these studies were limited to brief interventions such that the transfer and long-term effects of II training remains unclear. This study examined whether a 10-session II programme could improve PM performance, social functioning and functional capacity in patients with schizophrenia immediately after training and at 3-month follow-up. Patients with schizophrenia (n = 42) recruited from the community were randomly assigned to II training (n=21) or treatment as usual (TAU) (n=21). Participants in the II group learned the verbal and imagery component of II and were encouraged to apply these strategies in their daily lives. We found that the II group performed better than the TAU group on computer-based PM tasks and a daily life PM task (telephone call at specified date and time) at post-treatment and at 3-month follow-up. The II group also exhibited better working ability than the TAU group at post-treatment. Our results suggest that the II intervention programme may have lasting beneficial effects in PM performance and significant transfer effects to functional capacity in schizophrenia patients.

Abstract: PM dysfunction is an important impairment in individuals with schizophrenia, and more rehabilitation studies to improve PM performance in these individuals are needed.
