19 Possible Causes for Cortical Thinning, Slowing - Theta Waves

  • Alzheimer Disease

    Na, Dae Ryong Kang and Sang Won Seo, Higher education affects accelerated cortical thinning in Alzheimer's disease: a 5-year preliminary longitudinal study, International[dx.doi.org] ., posterior cingulate, precuneus, and/or temporoparietal cortices) on FDG-PET, and (3) cortical thinning/gray matter loss in a specific anatomic distribution (i.e., lateral[ncbi.nlm.nih.gov] Dysexecutive versus amnesic phenotypes of very mild Alzheimer’s disease are associated with distinct clinical, genetic and cortical thinning characteristics.[doi.org]

  • Traumatic Brain Injury

    Blast-Exposed Veterans With Mild Traumatic Brain Injury Show Greater Frontal Cortical Thinning and Poorer Executive Functioning .[doi.org]

  • Hydrocephalus

    Fetuses who develop progressive ventricular enlargement and cortical thinning from hydrocephalus before 28 weeks may have irreversible damage by 32 weeks.[chop.edu] A CT scan showed severe dilation of the brain’s lateral ventricles, while an MRI scan revealed massive enlargement of the lateral third and fourth venricles, a very thin cortical[sciencedaily.com] Prenatal factors such as progression, degree of cortical mantle thinning to less than 1.5 cm and in utero duration of greater than four weeks are associated with a poor prognosis[chop.edu]

  • Unverricht-Lundborg Syndrome

    Thus the progression of cortical thinning cannot be explained by age alone.[ajnr.org] Interictal wake EEG was notable for continuous, diffuse, often sharply contoured theta slowing and frequent, up to 200 μV, generalized, 4- to 5-Hz spike-wave and polyspike-wave[karger.com] Unverricht-Lundborg disease EEG findings reveal background slowing in theta frequency, with a 3-5 Hz polyspike, and waves discharge with sporadic focal spikes and wave discharges[emedicine.medscape.com]

  • Benign Familial Infantile Epilepsy

  • Attention Deficit Hyperactivity Disorder

    Slower cortical thinning during adolescence is characteristic of ADHD and provides neurobiological evidence for dimensionality.[emedicine.com] During inattentive or unfocused states, the slow theta waves (3.5–8.0 Hz) dominate the prefrontal and frontal cortices, as well as other midline loci of the brain.[mdpi.com] Some studies have concluded that responders to stimulant medications have an initial excess of slow wave (theta) activity.[mdpi.com]

  • Vascular Dementia

    thinning 41 and cortical atrophy, 42 which occurs 10 years before the onset of symptoms.[scielo.br] Prominent posterior slow-wave activity on EEG with periodic fluctuations in the pre-alpha/ theta range.[indianjpsychiatry.org] Incident subcortical infarcts induce focal thinning in connected cortical regions. Neurology. 2012;79(20):2025–8.[doi.org]

  • Normal Pressure Hydrocephalus

    The best predictors of outcome to include aqueductal flow void , thinning of the corpus callosum, effacement of the sulci with absence of cortical atrophy and gait apraxia[docneuro.com] In 13 cases the EEG was abnormal, the abnormality most frequently observed being a of the rhythmic slow wave type, consisting of bursts of monorhythmic theta or delta waves[link.springer.com] Evidence of cortical or hippocampal atrophy is not consistent with the diagnosis and degenerative diseases should be considered instead.[clinicaladvisor.com]

  • Attention Deficit Disorder

    During inattentive or unfocused states, the slow theta waves (3.5–8.0 Hz) dominate the prefrontal and frontal cortices, as well as other midline loci of the brain.[mdpi.com] Slower cortical thinning during adolescence is characteristic of ADHD and provides neurobiological evidence for dimensionality.[emedicine.com] Some studies have concluded that responders to stimulant medications have an initial excess of slow wave (theta) activity.[mdpi.com]

  • Adult Attention Deficit Disorder

    Cortical thinning of the attention and executive function networks in adults with attention-deficit/hyperactivity disorder.[ncbi.nlm.nih.gov] During inattentive or unfocused states, the slow theta waves (3.5–8.0 Hz) dominate the prefrontal and frontal cortices, as well as other midline loci of the brain.[mdpi.com] Slower cortical thinning during adolescence is characteristic of ADHD and provides neurobiological evidence for dimensionality.[emedicine.com]
