basal ganglia changes also in other movement disorders such as lenticular nucleus hyperechogenicity in idiopathic dystonia and Wilson's disease and caudate nucleus hyperechogenicity in Huntington's disease. Reduced echogenicity of midbrain raphe is frequent in depressive disorders and was found to correlate with responsivity to serotonin reuptake inhibitors.

Repetitive Transcranial Magnetic
Stimulation
(rTMS) is applied to enhance motor recovery by a non-invasive
deep
brain
stimulation
of motor cortex.
Both robotic devices and FES can be controlled or triggered by biological signals recorded from the patient. Such positive feedback loop can enhance learning. The new approaches as braincomputer interfacing (BCI) and Functional near infrared spectroscopy-based BCIs are under investigations [6].

Аn irreversible damage of tractus pallidothalamicus or nucleus ventralis intermedius thalami is caused, which can be achieved through both classical (stereotactic surgery, radiosurgery or
deep

) and MRgFUS methods.
Treatment with HIFU is indicated in drug-resistant forms of the disease for reducing the akinetic symptoms and/ or the tremor.
Аn irreversible damage of tractus pallidothalamicus or nucleus ventralis intermedius thalami is caused, which can be achieved through both classical (stereotactic surgery, radiosurgery or deep brain stimulation) and MRgFUS methods.
In contrast to classical methods, which have substantial disadvantages (invasiveness and increased radiation load), ultrasound thalamotomy or pallidotractotomy is a promising noninvasive method, which is currently applied in a small number of patients, mainly in clinical research.

TCS reliably and safely displays
deep
brain
stimulation
electrodes in patients with movement disorders and allows intraand postoperative monitoring of electrode location.
Hyperechogenicity of the substantia nigra (SN), a TCS finding seen in about 90% of patients with idiopathic Parkinson's disease (PD), is already present in presymptomatic disease stages and indicates an increased risk of developing PD, especially if present in combination with other risk markers. The TCS finding of SN hyperechogenicity well discriminates PD from other Parkinsonian disorders such as multiple-system atrophy and welding-related Parkinsonism. In turn, normal SN echogenicity in combination with lenticular nucleus hyperechogenicity indicates an atypical Parkinsonian syndrome rather than PD with a specificity of more than 95%. TCS detects characteristic basal ganglia changes also in other movement disorders such as lenticular nucleus hyperechogenicity in idiopathic dystonia and Wilson's disease and caudate nucleus hyperechogenicity in Huntington's disease. Reduced echogenicity of midbrain raphe is frequent in depressive disorders and correlated with both suicidal ideation and responsiveness to serotonin reuptake inhibitors.

Upcoming technologies such as digitized image analysis and TCS-MRI fusion imaging will promote novel diagnostic applications of TCS in neurodegenerative brain disorders.

also in other movement disorders such as lenticular nucleus hyperechogenicity in idiopathic dystonia and caudate nucleus hyperechogenicity in Huntington's disease [12]. Lenticular nucleus hyperechogenicity in Wilson’s disease has been proven histochemically to be caused by copper accumulation, while the same TCS finding is caused by iron accumulation in hereditary disorders with brain iron accumulation such as PKAN and MPAN [13]. Reduced echogenicity of midbrain raphe is frequent in depressive disorders and in migraineurs [1, 5].

(DBS) electrodes [14, 15].
In neurodegenerative diseases transtemporal TCS is usually carried out in standardized axial imaging planes. For some diagnostic questions TCS is additionally performed in semi-coronal and coronal or transfrontal axial und sagittal imaging planes [9], e.g.
for the assessment of corpus callosum or the localization of deep brain stimulation (DBS) electrodes [14, 15].
TCS findings can be categorized into two types. The first is the semi-quantitative or quantitative assessment of
