Psychogenic (dissociative) amnesia is a psychiatric disorder characterised by a sudden loss of memory which is too extensive to be explained by ordinary forgetfulness, but which has no organic disease or explanation. Psychogenic amnesia is categorised among the dissociative disorders in DSM-IV and ICD-10 and begins suddenly, usually after severe psychosocial stress. The prognosis is good with complete recovery, and there is seldom relapse. This article describes a man, 45 years of age, who developed severe depression and amnesia following a very troublesome divorce. He did not talk, he communicated by signs and gestures, and he isolated himself in his mother's home. After being admitted to a psychiatric ward he became anorectic and developed erosive eoesophagitis/gastroduodenitis. Initially he was given perfenazin (Trilafon) 24 mg/day. The psychiatric treatment produced no results for the first three weeks, but the patient gradually recovered when the therapist and the patient recapitulated the conflicts associated with the divorce, using documents from the patient's lawyer as a guide. This method is called "therapeutic anamnesis" and is similar in many ways to psychiatric treatment of post-traumatic stress reactions.

The term "mild cognitive impairment" refers to cognitive deficits which exceed normal physiological aging processes, but do not fulfill the criteria for dementia. While recent studies indicate that the respective deficits can be reliably assessed, different diagnostic criteria have prevented a wide application of this diagnosis in clinical practice. The aims of the present study were (1) to assess the prevalence rates of four current diagnostic concepts and (2) to investigate mild cognitive impairment with respect to psychological and sociodemographic variables. Data from 202 probands recruited from the interdisciplinary longitudinal study on adult development were analyzed. On the time of examination, probands were between 60 to 64 years old and in a good health. The following prevalence rates were determined: 13.5% for age-associated memory impairment (AAMI), 6.5% for age-consistent memory impairment (ACMI), 1.5% for late-life forgetfulness (LLF), and 23.5% for aging-associated cognitive decline (AACD). Complaints of cognitive deficits were significantly correlated with higher scores on depression and neuroticism scales but with none of the neuropsychological measures. Reduced performance in neuropsychological tests was associated with a lower educational level and socioeconomic status. We conclude that the prevalence rates of mild cognitive impairment are highly dependent on the diagnostic criteria applied. In this respect the self-report of cognitive decline might be a less useful criteria. Longitudinal studies are warranted to further elucidate the predictive value of these diagnostic criteria.

The term "mild cognitive impairment" refers to cognitive deficits which exceed normal physiological aging processes, but do not fulfill the criteria for dementia. The prevalence rates of four current concepts were compared in a sample of 202 healthy 60-64 year-old participants recruited from the interdisciplinary longitudinal study on adult development and aging (ILSE). Furthermore, the relationships between cognitive deficits and psychological and sociodemographic variables were examined. The following prevalence rates were determined: 13.5% for age-associated memory impairment, 6.5% for age-consistent memory impairment, 1.5% for late-life forgetfulness and 23.5% for aging-associated cognitive decline. Subjective cognitive complaints did not correlate with results obtained from neuropsychological tests. Significant correlations were however found between subjective cognitive complaints and higher scores on depression and neuroticism scales. Significant correlations were also found between a reduced test performance and a lower educational level and socioeconomic status. Longitudinal studies are warranted to further elucidate the predictive value of these diagnostic concepts.

About half of newly delivered mothers suffer a transient phase of emotional lability or sadness a few days after parturition around the 2nd and 5th day after delivery. The transitory psychopathology of the postpartum blues is similar to premenstrual tension, whose main symptom is irritability. The essence of the postpartum blues is not depression, but a sudden, fleeting and unexpected mood change with anxiousness, low spirits, tearfulness, confusion, poor concentration and forgetfulness. The aetiology of this disorder is unknown. It is well known that oestrogens and progesterone modify catecholamine concentration and the density of adrenergic, noradrenergic und dopaminergic receptors in the limbic structures of the central nervous system. But most of the neurochemical studies have not distinguished between postpartum blues and other forms of depression found in women and occurring postpartum. Those research groups who defined a group with a dysphoric peak in the early puerperium could not find a significant correlation between sex hormone levels, neurobiochemical data, and postpartum mood changes.

1. We examined 156 patients 33 years after CO poisoning occurred at the Miike Mikawa Mine, Fukuoka, Japan. The subjects were classified according to age as follows: between 55 and 59 years (n = 14), 60 and 69 years (n = 62), 70 and 79 years (n = 60), and 80 and 87 years (n = 18). The mean age was 69.2 years old. Concerning the duration of coma that occurred soon after the accident, 64 remained comatose from 0 to 6 hours, 46 from 6 to 12 hours and 46 from 12 to 48 hours. 2. Subjective symptoms were observed in 96.8% of the patients. Among them, forgetfulness was noted in 89.7%, followed by irritability in 66.7%, headache in 59.6%, insomnia in 55.8%, limb pain in 46.8%, dull head feeling in 42.9% and dizziness in 36.5%. 3. Intellectual disturbances were observed in 68.6% of the patients, including impression disturbance in 58.3%, memory disturbance in 51.9%, calculation disturbance in 63.5%, thinking disturbance in 61.5% and disorientation in 14.1%. 4. Apathy and disorder of volition and interest which were found in 72.4% were included in personality change because all symptoms persisted for many years. Personality change was classified as follows: weakness of emotion and will (hypobulia) in 54.4%, infantilism in 35.2%, hyperactive, talkactive and lack of inhibition in 18.5%, lack of self-possession and unstable temper in 9.6%, depression in 15.3%, neurosis in 7.6% and schizophrenic state in 2.5%. Among these symptoms of personality change, weakness of emotion and will and infantilism were conspicuous among the patients who remained in a coma for more than 6 hours soon after the accident but showed no relationship with age. 5. Neurological symptoms that were found in 48.7% of the patients were classified as sensory disturbance in 25.6%, peripheral nerve symptoms in 16.0%, pyramidal symptoms in 14.1%, ataxia and cranial nerve symptoms in 7.1%, paroxysmal symptoms in 6.4% and focal symptoms in 4.5%, extrapyramidal symptoms in 21.8% (Parkinsonism in 4.5%, tremor in 10.9% and muscle rigidity in 16.0%) and vegetative symptoms in 37.2%. 6. At the time of investigation, 5 CO poisoning patients were classified as serious cases (3.2%), 20 as comparatively serious (12.8%) medium-degree cases, 28 as comparatively mild (17.9%) medium-degree cases, 37 as comparatively serious (23.7%) mild cases, 42 as comparatively mild (26.9%) mild cases, 24 (15.4%) as having symptoms which were not problematic, and 24 (15.4%) as having symptoms that markedly worsened due to complication. 7. A total of 138 (88.4%) cases had complications were classified as follows: 78 cases (50.0%) of hypertension, 62 cases (39.7%) of cerebral infarction, 24 cases (15.4%) of cardiac disturbance, 21 cases (13.5%) of diabetes mellitus, 14 cases (9.0%) of hepatic disturbance and six cases of silicosis (3.8%). 8. Cranial MRI was carried out for 129 cases (82.7%). Of the abnormal findings identified, cerebral atrophy accounted for 72.0% (93 cases), including moderate and severe cases in 47.2% (61 cases), pallidum lesion for 37.9% (49 cases), lacunar infarction (including cerebral infarction) for 52.7% (68 cases), and hippocampal atrophy for 18.6% (24 cases). Many cases of cerebral atrophy and hippocampal atrophy were observed in patients who remained in the initial coma for more than 12 hours and were 80 years of age or old. The cases of pallidum lesion were observed in patients who remained in the initial coma for more than 6 hours, and no relationship with age was found. The other findings, cerebral atrophy and lacunar infarction showed a slight relationship with age. 9. Among the moderate and serious cases of intellectual disturbance, cerebral atrophy constituted to 62.5%, lacunar infarction 68.7% and pallidum lesion 50.0%. Among the moderate and serious cases of personality change, cerebral atrophy constituted 78.5%, lacunar infarction 35.0% and pallidum lesion 50.0%. Moreover, among extrapyramidal symptoms, pallidum lesion constituted 58.6%, cerebral atrophy 55.1% and lacun

In order to assess differences between self-assessment and clinician's assessment of depression, 64 depressed in-patients were assessed for depressive symptomatology at admission (D0), 10 days (D10) and 28 days (D28) after the beginning of antidepressant treatment, using the Inventory for Depressive Symptomatology Clinician Rated (IDS-C) and the Inventory for Depressive Symptomatology Self-Rated (IDS-SR). Associated symptoms (SCL-90R) were assessed at D0 and personality dimensions (TCI) at D28. Although agreement was high between IDS-C and IDS-SR total scores, D0, D0-D10 and D0-D28 total scores were significantly different between IDS-C and IDS-SR, showing a higher sensitivity to change for IDS-C as compared to IDS-SR. Differences between IDS-C and IDS-SR were due mostly to mood items and not to somatic items. Discrepancies between self-assessment and clinician's assessment of depressive symptomatology were linked neither to age, sex, familial status, single/recurrent and length of episode, nor to depression severity, but to associated symptoms and, to a lesser extent, personality dimensions: patients over-estimating their depressive symptomatology change relative to the psychiatrist tended to score high on phobic anxiety, Cooperativeness (especially Social Acceptance) and Self-Transcendence (especially Self-forgetfulness) and vice-versa.

This is a descriptive, correlational study of the predictors of perceived cognitive functioning. The convenience sample of 728 nonhospitalized persons receiving health care for HIV/AIDS was recruited from seven sites in the United States. All measures were self-reported. Self-perception of cognitive functioning, the dependent variable, was composed of three items from the Medical Outcomes Study HIV scale: thinking, attention, and forgetfulness. Data related to age, gender, ethnicity, education, injection drug use, CD4 count, and length of time known to be HIV-positive were collected on a demographic questionnaire. The scale from the Sign and Symptom Checklist for Persons with HIV Disease was used to measure self-reported symptoms. Data were analyzed using hierarchical multiple regression analysis. Predictors of perception of cognitive functioning explained a total of 36.3% of the variance. Four blocks--person variables (1.5%) (age, gender, education, history of injection drug use), disease status (2.3%), symptom status (26.5%), and functional status (5.4%)--significantly contributed statistically to the total variance. Among those individuals who completed the questions related to depression (n = 450), 28% of the variance in cognitive functioning was explained by this variable. The findings in this multi-site study indicate that symptom status explained the largest amount of variance in perceived cognitive functioning. Early identification of cognitive impairment can result in appropriate clinical interventions in remediable conditions and in the improvement of quality of life.

It has been recently reported that the female steroid hormone 17beta-estradiol enhances synaptic transmission and the magnitude of long-term potentiation (LTP) in adult rodent hippocampus. Moreover, 17beta-estradiol ameliorates cognitive and memory function in postmenopausal women. Since aging is associated with an alteration of synaptic plasticity (e.g., higher susceptibility to long-term depression [LTD]), we examined whether 17beta-estradiol alters the expression of LTD in aged rats. We now report that the induction of LTD recorded from CA1 hippocampal neurons of aged rats is suppressed by 17beta-estradiol treatment, which produced only a minimal effect in suppressing LTD in adult rats. These results suggest that estrogen may act to improve memory by suppressing forgetfulness via a synaptic mechanism, such as LTD.

Patients with chronic pain often complain of difficulties with cognitive functioning. Previous studies suggest that these occur with no history of head trauma or neurological disease. This study examined potential predictors of cognitive complaints in 275 consecutive patients referred to a university pain management center. Patients completed a brief set of self-report measures of problems with cognitive functioning, biographical information, pain severity, pain location, depression, anxiety, sleep quality, medication use, and litigation status during their first visit to the clinic. The most frequently reported cognitive complaints included forgetfulness (23.4%), minor accidents (23.1%), difficulty finishing tasks (20.5%), and difficulty with attention (18.7%). Fifty-four percent of patients reported at least one problem with cognitive functioning. Correlation analyses showed that using antidepressants, pain severity, pain-related anxiety, and depression were moderately associated with total cognitive complaints. Regression analyses showed that depression accounted for the largest unique proportion of variance in cognitive complaints (DeltaR2 = 29%). Given the high frequency of complaints of impaired cognitive functioning, this realm of functioning deserves routine assessment. When these complaints are encountered, a careful evaluation considering a range of neurological, social, and emotional influences is in order.

A 65-year-old woman was admitted to our hospital for forgetfulness, depression and eccentric behavior that had been first noticed 2 years prior to admission. She showed memory impairment, perseveration and repeated violent actions, but no limb-kinetic apraxia. She died 12 years after the onset of symptoms. At autopsy, the unfixed brain weighed 820 g. Atrophy was circumscribed in the frontal lobe on both sides. The globus pallidus and the caudate nucleus were markedly atrophic and gold yellow in color, and the substantia nigra was strikingly pale. The cortical area showed neuronal loss and status spongiosus of the second and third cortical layers with ballooned neurons. Marked neuronal loss was observed in the dorsomedial nucleus of the thalamus, Meynert basal nucleus and substantia nigra. With Holzer stain, fibrillary gliosis was found to be severe in the frontal lobe, globus pallidus, subthalamic nucleus, hippocampus, dorsomedial nucleus of thalamus, substantia nigra, pontine tegmentum and inferior olivary nucleus. With Bielschowsky-Hirano stain, neurofibrillary tangles were observed in the cortex, hippocampus, substantia nigra, dentate nucleus, subthalamic nucleus, pontine nucleus, the inferior olivary nucleus, dorsomedial nucleus of the thalamus and, to a lesser extent, the neostriatum. Strikingly numerous argyrophilic and tau-positive threads were present in the cerebral white matter. These neuropathological findings corresponded to corticobasal degeneration, but lesions characteristic of progressive supranuclear palsy were also found. Moreover, widespread iron deposition throughout the central nervous system was the most striking finding of the present case. To our knowledge, such a case has not been reported in the literature to date.
