Deficits in cognitive function may impact one's ability to attend to stimuli, think clearly, reason, and remember. Impaired cognitive function is a common complaint among older women presenting for treatment in both mental health and medical care settings, and differential diagnosis of type and extent of cognitive impairment is important for appropriate treatment planning and prognosis. Although overall gender differences in prevalence of cognitive dysfunction are minimal, it is important when treating older women to take into account unique challenges they face in the aging process that impact the cause, type and extent of cognitive complaints with which they present in clinical settings. The current paper provides an overview to guide accurate diagnosis, particularly in women, of different types of cognitive impairment under the broad category of dementias, including Alzheimer's, Lewy Body Disease, Vascular Dementia, and due to general medical conditions such as coronary artery bypass surgery, head injury, menopause, hypothyroidism, breast cancer treatment, Fibromyalgia, and chronic fatigue. In addition, emotional factors such as depression in older female patients complicate differential diagnosis of cognitive impairment and must be addressed. Given the multiplicity of causes of cognitive difficulties for women across the life span, careful assessment is crucial; the current paper reviews assessment strategies to prepare an integrated, biopsychosocial strategy for identifying particular cognitive deficits and related psychological and medical problems. In addition, prognostic indicators and treatment planning are discussed to help the practitioner organize an empathic, reasoned and multifaceted treatment approach to maximize recovery, minimize deterioration, and manage symptoms for older women in the context of their social support system and living environment.

Parkinson's disease (PD) is characterized by a progressive loss of nigrostriatal dopaminergic neurons associated with intracellular Lewy inclusion bodies. The result is poverty of movement, increased muscle rigidity, and tremor at rest and on posture. Midbrain/nigral structural abnormalities can be demonstrated in vivo with both transcranial sonography (TCS) and diffusion tensor magnetic resonance imaging (DTI) while positron emission tomography (PET) and single photon emission computed tomography (SPECT) ligands exist to demonstrate dopamine terminal dysfunction. These radiotracers are markers of dopamine storage capacity, vesicular monoamine and dopamine transporter availability. While loss of putamen dopaminergic function leads to motor disability, Lewy bodies not only target dopamine neurons but have also been observed in serotoninergic, noradrenergic, and cholinergic neurons. As a consequence, non-dopaminergic neurotransmission is also impaired resulting in non-motor symptoms including sleep disturbance, fatigue, depression, dementia, and autonomic dysfunction. PET and SPECT ligands exist to interrogate the function of monoaminergic and cholinergic neurons. Cortical and limbic Lewy body disease is seen in more advanced PD and this can be detected with FDG PET as abnormal covariance between levels of resting brain metabolism in these regions. Additionally, widespread microglial activation can be detected in PD with PET. This review discusses the role of structural and functional imaging for understanding parkinsonian syndromes and aiding in their diagnosis and management.

Introduction: We reviewed studies that assessed the treatment of psychiatric disturbances in Parkinson's disease and atypical parkinsonisms. Neuropsychiatric disturbances in these conditions are frequent and have a profound impact on quality of life of patients and of their caregivers. It is therefore important to be familiar with the appropriate pharmacological and non-pharmacological interventions for treating these disorders. Areas covered: The authors searched for papers in English in Pubmed using the following keywords: Parkinson's disease, multiple system atrophy, progressive supranuclear palsy, corticobasal degeneration, Lewy body dementia, depression, apathy, anxiety, fatigue, sleep disorders, obsessive compulsive disorders, psychosis, hallucinations, delusions, impulse control disorders. Expert opinion: In Parkinson's disease, depression may benefit from the optimization of dopaminergic therapy, from the use of antidepressants acting on both the serotoninergic and noradrenergic pathways and from cognitive behavioral therapy. Psychosis in Parkinson's disease may improve with the use of clozapine; the serotonin inverse agonist pimavanserin has been shown to be effective. Treatment of impulse control disorders is primarily based on the removal of dopamine agonists. No controlled studies have investigated the treatment of neuropsychiatric disorders in multiple system atrophy, progressive supranuclear palsy or corticobasal degeneration. Acethylcholinesterase inhibitors may be used to treat hallucinations in Lewy body dementia.

Patients with type 1 Gaucher disease (GD1) present thrombocytopenia, anemia, organomegaly, and bone complications. Most experts consider that the less aggressive forms do not require specific treatment. However, little is known about the disease course of these forms. The objective of this cross-sectional retrospective study was to compare the clinical, radiological, and laboratory characteristics of patients with less severe GD1 at diagnosis and at the last evaluation to identify features that might lead to potential complications. Non-splenectomized and never-treated patients (19 women and 17 men) were identified in the French Gaucher Disease Registry (FGDR). Their median age was 36.6 years (2.4-75.1), and their median follow-up was 7.8 years (0.4-32.4). Moreover, 38.7% were heterozygous for the GBA1 N370S variant, and 22.6% for the GBA1 L444P variant. From diagnosis to the last evaluation, GD1 did not worsen in 75% of these patients. Some parameters improved (fatigue and hemoglobin concentration), whereas platelet count and chitotriosidase level remained stable. In one patient (2.7%), Lewy body dementia was diagnosed at 46 years of age. Bone lesion onset was late and usually a single event in most patients. This analysis highlights the genotypic heterogeneity of this subgroup, in which disease could remain stable and even improve spontaneously. It also draws attention to the possible risk of Lewy body disease and late onset of bone complications, even if isolated, to be confirmed in larger series and with longer follow-up.
