About this study

Official title: Differences in Voxel-based Morphometry of Different Brain Structures in Patients With Mood Disorder Bipolar Mania in Comparison to Morphometry of Nrmal Controls

Bipolar disorder is a complex psychiatric disorder characterized by recurrent episodes of mania or hypomania and depression, and affects around one to three percent of the population . Bipolar Disorder is associated with significant psychosocial morbidity and mortality , and is among the leading causes of disability worldwide . The disease is highly heritable, but the underlying pathophysiology is not yet understood .

Read the detailed description

It is recognized that lesions in some specific neuro-anatomic areas due to brain disease, e.g., stroke or brain tumor, may lead to the development of secondary depression. The possibility of structural brain abnormalities as a cause of depression stimulated the use of structural brain imaging studies. Developments in structural neuroimaging by computed tomography and magnetic resonance imaging in the past 15 years facilitated the direct examination of specific brain structures, making the study of the relationship between anatomy and psychopathology is possible.

Neuro-anatomic model of mood regulation :

The prefrontal cortex has extensive connectivity to cortical and subcortical circuits that may underlie its importance in cognitive functions and modulation of limbic activity .The main subcortical structures participating in these circuits are the basal ganglia, thalamus, hypothalamus, brainstem, and the white matter tracts that connect these structures among themselves and to the cerebral cortex . A limbic-thalamic-cortical circuit consisting of the amygdala, the medio-dorsal nucleus of the thalamus, and the medial and ventro-lateral prefrontal cortex, and a limbic-striato-pallidal-thalamic circuit comprising the striatum, the ventral pallidum, and the components of the other circuit are the main neuro-anatomic circuits that have been proposed to participate in the pathophysiology of mood disorders.

The basal ganglia connect with cortical and limbic regions through circuits that, despite functioning segregated, are organized in parallel , in such a way that lesions in different parts of these circuits could result in malfunction. Additionally, the cerebellum, through connections with the brainstem and limbic structures, may also be involved in mood regulation.

Both primary and secondary mood disorders may involve abnormalities in specific fronto-subcortical neuro-anatomic circuits. Abnormalities in these brain regions or in contiguous areas that can affect the connections between these regions could reflect malfunction of these circuits, associated with development of mood disorders. Alternatively, abnormalities in these circuits could confer vulnerability to mood disorders, and its onset could be determined by interactions with environmental and genetic factors. Deficits during brain development due to these factors could result in under-development of particular brain areas, which could be related subsequently with mood disorders. The aging process or pathology such as vascular brain disease could result in atrophy of some of these regions. Thus, the influence of genetic, environmental, developmental, and degenerative factors during the development of these brain structures may determine the onset of mood disorders .

Although structural brain abnormalities in Bipolar Disorder have been reported, the pattern of structural brain abnormalities based on magnetic resonance imaging is still not clearly defined.

Aim of the study :

To study the morphometric criteria of different brain structures in patients with Bipolar Disorder type I mania in comparison to healthy subjects.

Subjects and Methods:

Patients :

Inclusion criteria:

Patients diagnosed to have mood disorder Bipolar I mania with or without psychotic features according to criteria of Diagnostic and statistical Manual of Mental disorder-IV (American Psychiatric Association 1994) by psychiatric sheath of psychiatric unit at Assiut University hospital .

The patients will be arranged in Two subgroups:

first group: twenty five patients in more than one episode second group: twenty age and sex-matched healthy subjects will be enrolled in the study

.

Exclusion Criteria:

first and second degree relatives of psychiatric patients will be excluded from the healthy controls.

Persons with any neurological disorder or other psychiatric illness will be excluded from controls Patients with proven major structural abnormality as detected during Magnetic resonance Imaging Examination will be excluded from patients or healthy controls.

Being tested
Magnetic resonance imaging

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Magnetic resonance imagingDiagnostic test

    A full Magnetic Resonance Imaging examination of the brain will be done for each of the subjects included in the study. The protocol of the study will include a high-resolution thin-cuts three Dimensions-T1 weighted gradient echo sequence to be used for the morphometric study.

    The obtained images will be analyzed for any gross structural abnormalities. by using fully-automated computational voxel-based volumetric software that calculates the volume of different structures of the brain. The obtained data will be analyzed statistically using linear regression tests to determine the differences between Bipolar Disorder type I mania patients and the healthy controls
