Generalist predators using small mammals as their primary prey are suggested to shift hunting alternative prey such as bird nests, when small mammals are in short supply (the alternative prey hypothesis, APH). Nest survival and survival of young individuals should be positively linked to small mammal abundance and negatively linked to predator abundance, but little information exists from survival of chicks, especially until recruitment. We test these predictions of the APH using 13 years (2002-2014) of life history data from a ground nesting shorebird breeding on coastal meadows.

Most of the available evidence on neuropsychological functioning in anxiety disorders is based on clinical samples, investigating persons affected by obsessive-compulsive disorder. Knowledge is sparse regarding cognitive functions in other types of anxiety disorders. The aim of this study was to examine whether persons diagnosed with an anxiety disorder show neuropsychological impairments relative to healthy controls in tasks tapping episodic memory, verbal fluency, psychomotor speed, and executive functioning.

Background: Most of the available evidence on the effects of depression is based on in- and out-patient samples focusing on individuals suffering from major depression. The aims of this study were to examine cognitive functioning in population-based samples and to determine whether cognitive performance varies as a function of depression subgroup.

Method: Population-based samples (aged 20-64 years) with major depression (N = 68), dysthymia (N = 28), mixed anxiety-depressive disorder (N = 25) and minor depression (N = 66) were examined on a variety of cognitive tasks (i.

Hereditary neuralgic amyotrophy (HNA) is an autosomal dominant, recurrent focal neuropathy. HNA is characterised by episodes of painful brachial plexus neuropathy with muscle weakness and atrophy, as well as sensory disturbances. Single episodes are commonly preceded by non-specific infections, immunisations or parturition.

We present the clinical and histopathological features and the diagnostic difficulties encountered in five children affected by a motor neuron disorder other than spinal muscular atrophy. Investigations performed suggested the diagnosis of ponto-cerebellar hypoplasia type 1 (PCH-1). Severe respiratory difficulty was present at birth in two of these children; hypotonia, arthrogryposis, microcephaly and nystagmus were present in all.

The impact of verbal and visuospatial ability on sex differences in episodic memory was investigated. One hundred men and 100 women, 2040 years old, participated in a series of verbal and visuospatial tasks. Episodic memory was assessed in tasks that, to a greater or lesser extent, were verbal or visuospatial in nature.

We compared event-related responses (ERPs) to non-attended frequent and intermittent auditory input in school-aged children and in young adults. In adults, both inputs elicited prominent auditory N100 responses at vertex. In children, intermittent stimulation evoked vertex responses with similar latency and refractoriness, whereas frequently delivered identical tones evoked responses on average at 240 ms.

Immaturity in water and electrolyte balance in the brain has been considered to increase the susceptibility of young animals and children to febrile convulsions (FCs). Arginine-vasopressin (AVP) is involved in the regulation of several centrally mediated events such as modulation of fever and the ease with which water permeates into and out of the brain. To evaluate the possible role of AVP in the control of water balance and susceptibility to convulsions during fever we measured the AVP concentration in the cerebrospinal fluid (CSF) and plasma of febrile children with or without convulsions.

Unlabelled: During acute febrile diseases mild disturbances of water and electrolyte balance occur frequently. It has been suggested that changes in electrolyte balance, in particular hyponatraemia, might predispose a child to convulsions during febrile illness; however, the changes of electrolytes in the CSF are not known. We have studied the effects of fever and convulsions on water and electrolyte balance in CSF and serum by measuring osmolality and electrolyte concentrations in children.

Fever plays an important role in causing disturbances in fluid and electrolyte balance. Hyponatraemia has been thought to enhance the susceptibility to seizures associated with febrile illnesses in childhood. We have studied serum electrolyte levels in children with simple and complicated febrile convulsions.

In febrile convulsions glucose concentrations are known to increase both in the blood and cerebrospinal fluid (CSF). The reason behind this increase is, however, incompletely understood. We have studied the effects of convulsion and fever on the CSF and blood glucose concentrations in four different groups of children: febrile and non-febrile children, with and without convulsions.

The causes of mental retardation (MR) were studied as part of a multidisciplinary epidemiological case-control study in 151 mentally retarded patients identified by screening four age cohorts (12,882 children) at 8-9 years of age in the province of Kuopio, Finland. The causes of MR in 77 severely retarded (SD < or = -3 SD) and 74 mildly retarded (-2 > SD > -3) children were divided into pre-, peri-, postnatal and unknown groups according to the probable time of onset. The causes were pre-, peri-, postnatal and unknown in 60%, 9%, 8% and 23%, and 22%, 1%, 3% and 74%, in the two populations, respectively.

Histamine is a neurotransmitter participating in many physiological functions and behavior, including control of arousal and modulation of the circadian rhythms. Diurnal variation in cerebrospinal fluid (CSF) levels of tele-methylhistamine (t-MH), the main histamine metabolite, has been detected in several animal studies. In humans, such changes have not been described.

Children with infantile spasms (IS) are generally treated with ACTH although little is known of the biochemical basis of the symptoms and the mechanism of this therapy. We have measured the concentrations of gamma-aminobutyric acid (GABA), homovanillic acid (HVA) and 5-hydroxyindoleacetic acid (5-HIAA) in the CSF of IS children, followed the effect of ACTH treatment on these parameters and correlated CSF GABA values with the cause of IS, cranial CT findings and antiepileptic treatment. While significant differences in GABA concentrations were found between the children with IS and those with febrile seizures or nonconvulsive symptoms, these could be accounted for by age, not the disease present.
