UNLABELLED There is a clear need for brief, but sensitive and specific, cognitive screening instruments as evidenced by the popularity of the Addenbrooke's Cognitive Examination (ACE). OBJECTIVES We aimed to validate an improved revision (the ACE-R) which incorporates five sub-domain scores (orientation/attention, memory, verbal fluency, language and(More)
BACKGROUND Riluzole 100 mg probably prolongs survival in patients with amyotrophic lateral sclerosis by about two months and the safety of the drug is not a major concern. The evidence from randomized controlled trials indicates that patients taking riluzole probably survive longer than patients taking placebo. The beneficial effects are very modest and the(More)
This study compared Panic Online (PO), an internet-based CBT intervention, to best-practice face-to-face CBT for people with panic disorder with or without agoraphobia. Eighty-six people with a primary diagnosis of panic disorder were recruited from Victoria, Australia. Participants were randomly assigned to either PO (n=46) or best practice face-to-face(More)
OBJECTIVE To assess the clinical course and prognosis in patients with behavioral-variant frontotemporal dementia (FTD) lacking evidence of brain atrophy on magnetic resonance imaging (MRI). DESIGN Patients were enrolled into this prospective cohort study over a period of 15 years; cognitive status, duration of symptoms, and behavioral indexes were(More)
Amyotrophic lateral sclerosis (ALS) is a relatively rare disease with a reported population incidence of between 1.5 and 2.5 per 100,000 per year. Over the past 10 years, the design of ALS epidemiological studies has evolved to focus on a prospective, population based methodology, employing the El Escorial criteria and multiple sources of data to ensure(More)
This study was an open trial evaluation of a 10-week therapist-assisted cognitive behavior therapy (CBT) internet intervention (PTSD Online) undertaken with people with a primary clinical diagnosis of posttraumatic stress disorder (PTSD) (n=22) at pre-assessment. Participants were re-assessed at post-assessment and 3-month follow-up. Significant(More)
BACKGROUND We explored the applicability of recently proposed research criteria for mild cognitive impairment (MCI) in a memory clinic and changes in case definition related to which memory tests are used and the status of general cognitive function in MCI. METHOD A total of 166 consecutive GP referrals to the Cambridge Memory Clinic underwent(More)
Posttraumatic stress disorder (PTSD) is a debilitating mental health condition frequently associated with psychiatric comorbidity and diminished quality of life, and it typically follows a chronic, often lifelong, course. Previous research has shown that trauma-related psychopathology (but not necessarily clinical PTSD) can be effectively treated via the(More)
Although it is well recognized that MCI represents a risk state for subsequent dementia, estimates of conversion vary widely according to the diagnostic criteria employed. There are currently no simple cognitive predictors of high and low risk of progression. We followed 107 non-demented non-depressed subjects from an original cohort of 124—sub-classified(More)
Internet-based interventions with therapist support have proven effective for treating a range of mental health conditions. This study examined whether frequency of therapist contact affected treatment outcomes. Fifty-seven people with panic disorder (including 32 with agoraphobia) were randomly allocated to an 8-week Internet-based cognitive behavioural(More)
